Just to clarify my thinking, my working hypothesis is that there's the following mix going on in the PdD case (although not necessarily other cases):
- Induced fission of heavy nuclei into lighter nuclei through some mechanism, possibly involving electron screening, yielding the bulk of the measurable heat
- Induced decay of alpha emitters and potential alpha emitters, not producing much heat but yielding measurable helium
- Beta decay of short-lived beta emitters which are daughters of the preceding two processes that are somewhat too far from the line of stability
So although I have a mechanism vaguely in mind and have been tossing around different ideas with people who are more knowledgeable about the mechanics of the nuclear interactions, I have few specific reactions in mind (although there is one that falls under the second bullet point involving platinum, which is generally present in electrolytic experiments as the anode).
OK, so it would be helpful to have the specific reactions.
As I understand it you suppose there are (at least) two distinct nuclear reactions not normally expected which happen in these LENR experiments?
