Here is a paper on Ni isotope fractionation in meteorites.

Russia is the world's largest nickel producer and much of it comes from meteorite impact sites. This nickel can be naturally enriched, substantially in 64Ni, which is the process alled fractionation. This is exactly what could have happened with the Parkhomov nickel and he may not have realized this before now, based on the lack of further information in the paper.
Needless to say, the situation boils down to this. If you believe Rossi, then 62Ni would be active, but if you believe Parkhomov, then 64Ni is the isotope that works. I do not think it could be both based on Parkhomov's results.
Based on everything I have read, Parkhomov would be the one I would choose, especially since the theory behind 64Ni is stronger, and since 64Ni is a singularity of sorts, in terms of neutron heaviness. Plus the naturally enriched version should be much cheaper than buying pure isotope...
