But I think Robin speculated that that might be due to a secondary fissioning of neutron-heavy nuclei rather than the primary LENR reaction. I just looked at a table summarizing thirteen studies in which isotope shifts were seen (courtesy of Ed Storms's LENR book). There were maybe ten to twenty different isotopes seen between the different studies. Only two of the isotopes were highly radioactive -- beryllium-11 and titanium-40. The rest were stable or observationally stable or had a half-life of 10^9 years. The interesting thing is that there were both increases and decreases reported, and both were of relatively stable isotopes. Two studies reported transitions to highly radioactive species; beryllium-11 in one case and titanium-40 in the other. Both studies shared at least one collaborator, and the large number of shifts in one of the studies leads me wonder about contamination, although this is obviously not my area of expertise. These details give reason to think that you're right that shifts involve stable isotopes. I will be following the question of unstable isotopes more closely now. Jones made this point about isotopes sometime back, and I didn't appreciate that tritium might be a special case. Eric
