Recent accelerator experiments on fusion of various elements have clearly demonstrated that the effective cross-sections of these reactions depend on what material the target particle is placed in. In these experiments, there was a significant increase in the probability of interaction when target nuclei are imbedded in a conducting crystal or are a part of it. These experiments open a new perspective on the problem of so-called cold nuclear fusion.

PACS.: 25.45 – deuterium induced reactions
Submitted to Physics of Atomic Nuclei/Yadernaya Fizika in Russian

Experiments of Fleischmann and Pons made about 20 years ago [1], raised the question about the possibility of nuclear DD fusion at room temperature. Conflicting results of numerous experiments that followed, dampened the initial euphoria, and the scientific community quickly came to common belief, that the results of [1] are erroneous. One of the convincing arguments of skeptics was the lack in these experiments of evidence of nuclear decay products. It was assumed that “if there are no neutrons, therefore is no fusion.” However, quite a large international group of physicists, currently a total of about 100-150 people, continues to work in this direction. To date, these enthusiasts have accumulated considerable experience in the field. The leading group of physicists working in this direction, in our opinion, is the group led by Dr. M. McKubre [2]. Interesting results were also obtained in the group of Dr. Y. Arata [3]. Despite some setbacks with the repeatability of results, these researchers still believe in the existence of the effect of cold fusion, even though they do not fully understand its nature.  Some time ago we proposed a possible mechanism to explain the results of cold fusion of deuterium [4]. This work considered a possible mechanism of acceleration of deuterium contaminant atoms in the crystals through the interaction of atoms with long-wavelength lattice vibrations in deformed parts of the crystal. Estimates have shown that even if a very small portion of the impurity atoms (~105) get involved in this process and acquires a few keV energy, this will be sufficient to describe the energy released in experiments [2].  This work also hypothesized that the lifetime of the intermediate nucleus increases with decreasing energy of its excitation, so that so-called “radiation-less cooling” of the excited nucleus becomes possible. In [5], we set out a more detailed examination of the process.  Quite recently, a sharp increase of the probability of fusion of various elements was found in accelerator experiments for the cases when the target particles are either imbedded in a metal crystal or are a part of the conducting crystal. These experiments compel us to look afresh on the problem of cold fusion.

Recent experiments on fusion of elements on accelerators
For atom-atom collisions the expression of the probability of penetration through a Coulomb barrier for bare nuclei should be modified, because atomic electrons screen the repulsion effect of nuclear charge. Such a modification for the isolated atom collisions has been performed in H.J. Assenbaum and others [6] using static Born-Oppenheimer approximation. The experimental results that shed further light on this problem were obtained in relatively recent works C. Rolfs [7] and K. Czerski [8]. Review of earlier studies on this subject is contained in the work of L. Bogdanova [9]. In these studies a somewhat unusual phenomenon was observed: the sub-barrier fusion cross sections of elements depend strongly on the physical state of the matter in which these processes are taking place. Figure 1 (left) shows the experimental data [8], demonstrating the dependence of the astrophysical factor S(E) for the fusion of elements of sub-threshold nuclear reaction on the aggregate state of the matter that contains the target nucleus 7Li. The same figure (right) presents similar data [7] for the DD reaction, when the target nucleus was embedded in a zirconium crystal. It must be noted that the physical nature of the phenomenon of increasing cross synthesis of elements in the case where this process occurs in the conductor crystal lattice is still not completely clear.

Figure 1. Up – experimental data [8], showing the energy dependence of the S-factor for sub-threshold nuclear reaction on the aggregate state of matter that contains the nucleus 7Li.  Down – the similar data [7] for the reaction of DD, when the target nucleus is placed in a crystal of zirconium. The data are well described by the introduction of the screening potential of about 300 eV.

The phenomenon is apparently due to the strong anisotropy of the electrical fields of the crystal lattice in the presence of free conduction electrons. Data for zirconium crystals for the DD reactions can be well described by the introduction of the screening potential of about 300 eV. It is natural to assume that the corresponding distance between of two atoms of deuterium in these circumstances is less than the molecular size of deuterium. In the case of the screening potential of 300 eV, the distance of convergence of deuterium atoms is ~510ˆ12 m, which is about an order of magnitude smaller than the size of a molecule of deuterium, where the screening potential is 27 eV. As it turned out, the reaction rate for DD fusion in these conditions is quite sufficient to describe the experimental results of McKubre and others [2]. Below we present the calculation of the rate process similar to the mu-catalysis where, instead of the exchange interaction by the muon, the factor of bringing together two deuterons is the effect of conduction electrons and the lattice of the crystal.

Calculation of the DD fusion rate for “Metal-Crystal” catalysis
The expression for the cross section of synthesis in the collision of two nuclei can be written as

where for the DD fusion

Here the energy E is shown in keV in the center of mass. S(E) astrophysical factor (at low energies it can be considered constant), the factor 1/E reflects de Broglie dependence of cross section on energy. The main energy dependence of the fusion is contained in an expression

that determines the probability of penetration of the deuteron through the Coulomb barrier. From the above expressions, it is evident that in the case of DD collisions and in the case of DDμcatalysis, the physics of the processes is the same. We use this fact to determine the probability of DD fusion in the case of the “metal-crystalline” DD-catalysis.  In the case of DDμ- catalysis the size of the muon deuterium molecules (ion+) is ~5×10ˆ13m. Deuterium nuclei approach such a distance at a kinetic energy ~3 keV. Using the expression (1), we found that the ratio of σ(3.0 keV)/σ(0.3 keV) = 1.05×10ˆ16. It should be noted that for the free deuterium molecule this ratio [ σ(3.0keV)/σ(0.03keV)] is about 10ˆ73.  Experimental estimations of the fusion rate for the (DDμ)+ case presented in the paper by Hale [10]:

Thus, we obtain for the “metal-crystalline” catalysis DD fusion rate (for zirconium case):

Is this enough to explain the experiments on cold fusion? We suppose that a screening potential for palladium is about the same as for zirconium. 1 cmˆ3 (12.6 g) of palladium contains 6.0210ˆ23(12.6/106.4) = 0.710ˆ23 atoms. Fraction of crystalline cells with dual (or more) the number of deuterium atoms at a ratio of D: Pd ~1:1 is the case in the experiments [2] ~0.25 (e.g., for Poisson distribution). Crystal cell containing deuterium atoms 0 or 1, in the sense of a fusion reaction, we consider as “passive”. Thus, the number of “active” deuterium cells in 1 cmˆ3 of palladium is equal to 1.810ˆ22. In this case, in a 1 cmˆ3 of palladium the reaction rate will be

this corresponds to the energy release of about 3 kW. This is quite sufficient to explain the results of McKubre group [2]. Most promising version for practical applications would be Platinum (Pt) crystals, where the screening potential for d(d,p)t fusion at room temperature is about 675 eV [11]. In this case, DD fusion rate would be:

The problem of “nonradiative” release of nuclear fusion energy
As we have already noted, the virtual absence of conventional nuclear decay products of the compound nucleus was widely regarded as one of the paradoxes of DD fusion with the formation of 4He in the experiments [2]. We proposed the explanation of this paradox in [4]. We believe that after penetration through the Coulomb barrier at low energies and the materialization of the two deuterons in a potential well, these deuterons retain their identity for some time. This time defines the frequency of further nuclear reactions. Figure 2 schematically illustrates the mechanism of this process. After penetration into the compound nucleus at a very low energy, the deuterons happen to be in a quasi-stabile state seating in the opposite potential wells. In principle, this system is a dual “electromagnetic-nuclear” oscillator. In this oscillator the total kinetic energy of the deuteron turns into potential energy of the oscillator, and vice versa. In the case of very low-energy, the amplitude of oscillations is small, and the reactions with nucleon exchange are suppressed.

Fig. 2. Schematic illustration of the mechanism of the nuclear decay frequency dependence on the compound nucleus 4He* excitation energy for the merging deuterons is presented. The diagram illustrates the shape of the potential well of the compound nucleus. The edges of the potential well are defined by the strong interaction, the dependence at short distances  Coulomb repulsion.

The lifetime of the excited 4He* nucleus can be considered in the formalism of the usual radioactive decay. In this case,

Here ν is the decay frequency, i.e., the reciprocal of the decay time τ. According to our hypothesis, the decay rate is a function of excitation energy of the compound nucleus E. Approximating with the first two terms of the polynomial expansion, we have:

Here ν° is the decay frequency at asymptotically low excitation energy. According to quantum-mechanical considerations, the wave functions of deuterons do not completely disappear with decreasing energy, as illustrated by the introduction of the term ν°. The second term of the expansion describes the linear dependence of the frequency decay on the excitation energy. The characteristic nuclear frequency is usually about 10ˆ22  sˆ-1. In fusion reaction D+D4He there is a broad resonance at an energy around 8 MeV. Simple estimates by the width of the resonance and the uncertainty relation gives a lifetime of the intermediate state of about 0.810ˆ22 s. The “nuclear” reaction rate falls approximately linearly with decreasing energy. Apparently, a group of McKubre [2] operates in an effective energy range below 2 keV in the c.m.s. Thus, in these experiments, the excitation energy is at least 4×10ˆ3 times less than in the resonance region. We assume that the rate of nuclear decay is that many times smaller. The corresponding lifetime is less than 0.3×10ˆ18 s. This fall in the nuclear reaction rate has little effect on the ratio of output decay channels of the compound nucleus, but down to a certain limit. This limit is about 6 keV. A compound nucleus at this energy is no longer an isolated system, since virtual photons from the 4He* can reach to the nearest electron and carry the excitation energy of the compound nucleus. The total angular momentum carried by the virtual photons can be zero, so this process is not prohibited. For the distance to the nearest electron, we chose the radius of the electrons in the helium atom (3.1×10ˆ11 m). From the uncertainty relations, duration of this process is about 10ˆ-19 seconds. In the case of “metal-crystalline” catalysis the distance to the nearest electrons can be significantly less and the process of dissipation of energy will go faster. It is assumed that after an exchange of multiple virtual photons with the electrons of the environment the relatively small excitation energy of compound nucleus 4He* vanishes, and the frequency of the compound nucleus decaying with the emission of nucleons will be determined only by the term ν°. For convenience, we assume that this value is no more than 10ˆ12-10ˆ14 per second. In this case, the serial exchange of virtual photons with the electrons of the environment in a time of about 10ˆ-16 will lead to the loss of ~4 MeV from the compound nucleus (after which decays with emission of nucleons are energetically forbidden), and then additional exchange will lead to the loss of all of the free energy of the compound nucleus (24 MeV) and finally the nucleus will be in the 4He ground state.  The energy dissipation mechanism of the compound nucleus 4He* with virtual photons, discussed above, naturally raises the question of the electromagnetic-nuclear structure of the excited compound nucleus.

Fig. 3. Possible energy diagram of the excited 4He* nucleus is presented.

Figure 3 represents a possible energy structure of the excited 4He* nucleus and changes of its spatial configuration in the process of releasing of excitation energy. Investigation of this process might be useful to study the quark-gluon dynamics and the structure of the nucleus.

Perhaps, in this long-standing history of cold fusion, finally the mystery of this curious and enigmatic phenomenon is gradually being opened. Besides possible benefits that the practical application of this discovery will bring, the scientific community should take into account the sociological lessons that we have gained during such a long ordeal of rejection of this brilliant, though largely accidental, scientific discovery. We would like to express the special appreciation to the scientists that actively resisted the negative verdict imposed about twenty years ago on this topic by the vast majority of nuclear physicists.

    The Green Eyed Monster Meets Rossi’s E-Cat


    It is the desire to have what belongs to someone else.

    Without a doubt, it is an emotion that can cause great harm, if not properly controlled.

    When allowed to grow unchecked, this emotion has broken up families, made enemies of neighbors, created workplace turmoil, and induced warfare between nations. In the alternative energy scene, it has created conflict between inventors who have similar goals. Quite often, the goal is to introduce a game changing technology to the world, and earn a financial reward to compensate for all the effort and sacrifice.

    In the case of the E-Cat technology, Andrea Rossi has what cold fusion researchers have only dreamed could exist. He has produced a cold fusion technology that produces a huge amount of output. Actually, it produces so much output it can melt the nickel powder and destroy all the reaction sites — making a reactor cease functioning. Instead of struggling to get five, ten, or fifteen watts, Rossi can produce more than ten kilowatts from a 50cc reactor core. The output of an E-Cat is phenomenal. It is beyond the dreams of most cold fusion researchers.

    What is also interesting, is that the E-Cat technology can self sustain without an input. Of course this has been achieved before, but never with a high level of output. In fact, Rossi has to throttle down his reactors in self sustain mode (by reducing hydrogen pressure) just so they don’t “run away” and melt the nickel powder. Instead of dying out in self sustain mode, they have a tendency to produce more and more power.

    In addition to being powerful and capable to self sustain, the E-Cat utilizes cheap nickel instead of expensive palladium, and cheap light hydrogen instead of deuterium. This means the technology is economically viable, because the fuel cost is almost non existent. Even the catalyst is said to only add 1/10th to the cost of the nickel powder.

    Now since such a powerful and robust technology exists, other cold fusion researchers are becoming jealous. They have not been able to achieve anything close to what Rossi has been able to achieve. If they are lucky, they may be able to produce tens of watts, max. Often, they are not able to do so with cheap fuels and have to resort to heavy hydrogen or expensive precious metals. With the E-Cat technology looming over them, their lack of being able to develop a practical cold fusion technology is becoming very frustrating.

    Instead of congratulating Rossi or applauding him for the technological breakthrough of the century, it seems as if his competitors have banded together to attack him. On websites and forums they slander him, mock him, and call him names. Despite the huge amount of evidence that he is producing massive amounts of excess heat, they claim he is a “fraud” and has proven “nothing.”

    A few of them have been jumping to make negative remarks in the comment section of every positive article posted about the E-Cat technology. It seems that jealousy and envy of what they have not been able to achieve, has taken them over. They are no longer curious, scientific researchers, but are now naysaying zombies. They seek to chew on any positive remark about the E-Cat, like the undead limp towards human brain matter. These obviously capable and intelligent individuals have let their emotions take over them, and are belittling a technology they should be rejoicing about.

    Obviously, there is probably a bit more than jealousy behind the actions and statements of some of these individuals. A couple of them obviously have pet theories they have been pushing for years. Since Rossi rejected (W-L) the theory on his blog, they feel obligated to go on the attack. Others probably feel that since Rossi’s patent protection may not be as solid as it could be, by attacking him they may be able to “buy time” to figure out how the E-Cat technology works. Then they may be able to patent it themselves, and claim “they” invented it — when it was Rossi’s all along. Then others probably feel jealous of Rossi because they were working on nickel-hydrogen cold fusion years ago. However, their systems were nothing like Rossi’s, and they did not get anywhere near the results. So now they are hiring lawyers, trying to block patents, and seeking to get what they feel is “owed” to them, even though they did not come up with the breakthroughs themselves.

    Once again, none of these jealous parties were responsible for developing the E-Cat technology.

    Only Rossi should get the credit.

    He was the one that came up with the right combination of nickel isotopes, the right combination of catalyst(s), the right size of nickel powder, the right processes to create tubercles on the nickel powder, the correct frequencies for the RFG to emit, and other elements that make the E-Cat the Holy Grail of cold fusion.

    It is his “secret sauce” and if anyone else wants to take credit, they should stop running their mouths, stop making posts that defy logic, stop telling flat out lies, stop slandering Rossi, and demonstrate something that can even come *close* to the output of an E-Cat.

    Of course they cannot, yet. And their failure to be able to produce anything close to the E-Cat is what fuels their jealousy and envy.

    By the way, Rossi is not perfect. We all have faults, and Rossi is the same. But his technology is darn close to a perfect energy source for mankind. I would urge all of the jealous competitors and researchers to either put away their jealousy and congratulate Rossi for his accomplishment, or back away. Even if someone has a personal issue with Rossi, they should not let it influence their opinion of the technology itself. If they want to keep attacking Rossi they risk being on the wrong side of history. The text books many years from now may not leave them a legacy they would want their grandkids to read about.

    I think somewhere, deep down inside, even those who have been attacking Rossi out of jealousy want a better world, and a better future for humanity. I find it sad that they have let jealousy and envy make them lose sight of why they become interested in cold fusion research to begin with. Perhaps if they would take a step back and consider the big picture — ignoring their personal ambitions — they would realize their attacks against the E-Cat technology are not helpful in creating a better home for all humanity.

    Dear Mr. Rossi,

    The UK Govt. has just announced a new 1 million pound for engineering excellence that will be awarded every two years with nominations for the first prize opening in February (to be awarded in spring 2013). It is meant to be the Nobel prize equivalent for engineering. Like the Nobel prize it is also international.

    This is yours for the taking. Do you think you will have any clients in 2012 who will be prepared to go public?

    All the best

    Dear Mister Rossi;
    With your self sustaining cold fusion project up and running was wondering if it was possible to have a two step cold fusion process were the sodium chloride in seawater could be converted to magnesium and the magnesium converted into aluminum. The present manufacture of aluminum takes a large amount of electrical power. A self sustaining cold fusion process would take very little power.

    Dear Rossi,

    One last question…This says

    “Andrea Rossi:

    We are building a 130 MW thermal plant, made of 13 plant such as the one you saw on October 28th: but it’s a military research and I can’t reveal any further detail, not the name, nor the place, nor the nationality of the customer

    The one that you ran on the 28th of Oct was 1 mw, so 13 of those is 13 mw…So is this a typo?

    Dear Mister Rossi,
    I’m following your ecat adventure since 15 january and I am so happy that things are going (more or less) as you planned (I kept my fingers crossed all time).
    I have to thank you to make me dreaming.
    I’m a father of two little kids and I’m telling them that there is a fantastic italian inventor that will give them a cleaner world with more opportunities for the humanity.
    One question: did you never seen the Walt Disney movie “MEET THE ROBINSON”, Your effort make me always thinking this movie.

    Last thing, I’m a Supply Chain Manager for a big company and I can only imagine how will be complicated to organize a world wide logistic and fulfillment network and operation.
    In case you will need help on Supply Chain staff, please remind my email I will be glad to offer my experience for this project (and tell my kids I have a little little part on that revolution).

    Dear Mr Rossi,
    Thank you for helping me:)so there are my questions.

    1. Do You remember the day when it turned out that e-cat is working and You succeeded? I’m very curious what did You think? Your first thought. First feelings.
    2. Is anything changed in Your life since then? Have You ever regret it?
    3. Do you still belive the e-cat could change the world the way we can’t really imagine?
    4. You said, that no one have proposed the money for buying the e-cat and making it disappeared? Is this still true?

    Thank you again.
    Maybe this questions will seem naive or not important at all, but this was my idea to get to know you better a little:)
    Actualy this questions could be one: Mr Rossi how to live after e-cat?:)

    The site is now saying it is “In Association with Andrea Rossi”. They have an order form for E-Cats, also. Do you have an official relationship with this site?

    Thank you!

    Best wishes,

  • Dear A. Rossi, ritorno a farti la stessa domanda di prima. Quando sarà disponibile per noi utenti l’E-cat per uso domestico, cioè quello di 3 o 5 kwatt? Come posiamo prenotarci per l’acquisto? Puoi essere più preciso?

    I’m writing an article which will be telling about e-cat and it will change world we know.
    I have some very simple questions to you but not about any technical specification.

    Do you knew about that?

    Dear Mr. Rossi

    Could you elaborate more regarding: “One of the main goals of mine is to generate jobs in the USA. I will, you bet. Just stay in touch. Next week I will have a very important work to do in this sense.”

    I think it would be important to know more about it.

    Thank you for the consideration.

  • Dear Mr. Rossi,

    We here in Brooklyn are very eager for the success of the E-Cat. Many of us would be very interested in the installation and service component of this technology in the New York City area. As you are aware, the employment crisis in the United States could accommodate the many green jobs that your technology could create. Thanks for keeping us all informed of your progress.

    Continued success,


  • Andrea Rossi

    Dear Charlie Sutherland:
