Sure:
58Ni+ 5p ->63Cu + 45MeV (some of that in gammas)
and
60Ni + 3p ->63Cu +25MeV (some of that in gammas)
I am ignoring the other natural Isotopes of Ni. But you get the idea. Also this is the net reaction as they claim (a stable Cu isotope is what they claim). This disregards the beta- decays required as stated in my earlier post.
