To answer your question in the dead thread about the cold fusion scam: Ni-64 (n,g) Ni-65 (e-,) Cu-65 is physical, and Cu-65 has a greater binding energy than Ni-64:
The binding energy per nucleon is lower, as the other guy points out, but that's the wrong metric because Cu-65 has one more nucleon. The free neutron coming in has zero binding energy.

(look at Δ(MeV), the mass excess)
