Contextual details -- such as the media handling -- pretty much convinced me that Rossi is a con artist shoveling big steaming loads ... but, of course, my contextual conclusions lack scientific merit
So I hunted the web some for anything that might indicate more precisely what Rossi is doing, or what Rossi says he is doing, or what various people say Rossi has told them he is doing, or what various people guess Rossi might be doing
As far as I can tell, we're being told that finely divided Ni in an H2 atmosphere undergoes nuclear reactions Ni + p -> Cu with rate controllable by H2 pressure
Details beyond this are sketchy
Unfortunately, I can't distinguish what Rossi might have told some people from other people's speculations: the clearest statement, that I've found so far, claims Rossi uses Ni enriched significantly in Ni-62 and Ni-64 together with some cheap catalyst to encourage the nuclear reaction
But this use of the common word "catalyst" seems unusual: I expect the primary energy barrier to be electrostatic repulsion between Ni nucleus and proton, and I can't see how ordinary chemical interactions (which affect the electron shell) to reduce this repulsion enough to allow Ni + p to proceed
The nucleon numbers in the possible reactions are nowhere near the magic numbers of nuclear shell theory, so I can't see why Ni + p capture should be favorable. But I haven't found an online table showing data for nuclear reactions of Ni and Cu isotopes: that would be useful to have, for example, when considering the common objection that there seems to be no significant radiation
Of course, there might be other possibilities. So one might want to know how permeable a Ni or Ni-Cu lattice is to proton and how stably a proton might be trapped in the lattice
If anyone knows of relevant resources on this, I'd be happy for the references
