All kinds of information nuclear reactions and decay is available in "Nuclides and Isotopes", a chart of the nuclides published by KAPL (Knowles Atomic Power Laboratory). I recommend the "chart" in book form as it comes with a bunch of nuclear physics discussion. Based on the description in the article Ni+n=Cu+e. There is only one stable isotope of Ni that has a chance of going through this process and resulting in a stable isotope of copper and that is Ni62. Ni62 is only 3.63% of naturally occurring nickle. The most abundant isotope is Ni58 (68.07%) and it will go to Ni59 with addition of a neutron and will beta decay to Co59. Ni59 has a 7600 year half life so you could continue to change it to Ni60 then Ni61 then Ni62, but all of this wouldn't happen instantaneously as stated in the article (I guess you could start an enrichment plant so you are only using Ni62, but that cost a lot of money and energy and would have to be factored into the energy balance of the final "reactor"). These types of reactions don't take place in nature because the stable isotopes are already at the bottom of the "valley of stability" (have a minimum mass or maximum binding energy, see pages 27-28 of the 16th edition of the "Nuclides and Isotopes"). I guess it is possible that the 30THz vibrations change the local laws of physics, but I will remain skeptical until there is more than speculation. The article states, "LENR is a very long way from the day when you can go out and buy a home nuclear reactor. In fact, it still has to be proven that the phenomenon even exists, but hundreds of experiments worldwide indicate that heat and transmutations with minimal radiation and low energy input do take place with yields of 10 to 100 watts." TFA states that they are not even sure if the phenomenon exists and it doesn't provide the total energy input to the system so you can't tell if 10-100W is noise or error in the measuring equipment (this is one of the things that was going on in the cold fusion of years past).
