Axil-- You have stated:
<<<<"IMHO, all fusing nuclei input to the LENR reaction must have zero spin. <<<<All isotopes of Cu have non zero spins and therefore are non reactive in LENR fusion. Cu will produce RF as being NMR active." Why do you think non-zero spin isotopes of Ni and Cu are LENR inactive and/or fusing nuclei input to the LENR reaction must have zero spin.? I think that if spin coupling occurs, spin and its angular momentum can be swapped among all coupled particles. However, it must be conserved IMHO. I can imagine that 2 Ni isotopes of Ni could change the sign of their spin in a magnetic field and pair up as a Cooper pair, much like electrons and protons pair up with spin in opposite directions. The net spin and angular momentum would be zero. Such a pair may react readily with other paired particles, for example, paired H or D particles. LENR is not fully understood yet.

But as you know beta-delayed gammas are a frequent occurrence. The half-life of the beta decay in this case is 100 years, so if there is beta-delayed gamma emission, the activity would be significant. The excited state after a beta- decay would be in the daughter (63Cu) not the parent (63Ni). I don't see any evidence for a 63Cu* excited state. You are probably right. Embarrassing rookie error on my part. Eric
