From: DJ Cravens Ni-62 If we assume that speculation about Rossi is correct, what materials other than Ni-62 could be used? If it is p + X reaction, what other isotopes other than Ni62 could be used? Or perhaps it is really a p+p reaction with Ni-62 donating something??? Anyone have any suggestions? This is an important point - is there a substitute for Ni-62? The best way to approach the subject is to look at the isotope and ask - is there anything which is unique about this species? Then, if the answer is "yes" we must ask - how does the unique property materialize in the gainful reaction? As to the first part - yes - Ni-62 is a singularity in the periodic table, being the one isotope with the highest binding energy per nucleon of all known nuclides (~8.8 MeV per) ... and yet here it is being identified as active for the anomalous energy Rossi claims to have found with hydrogen. On the one hand, if there is true gain in this device primarily due to properties of this isotope - being a singularity could be an important clue. OTOH it is most surprising that the physical property for which it derives its uniqueness - is the opposite of what one logically expects in the situation. That property, which is "highest binding energy" means the isotope is the most stable. What is the next most stable? That would be an iron isotope, but iron could have chemical properties which interfere with the nuclear reaction As for Part-2 of the inquiry... which is "why" ... this has been addressed piecemeal in prior postings, and I will collect these, with revisions, in another posting.
