Eric-- I would have said you need particles like H with an intrinsic spin to couple to the magnetic field. I think that 0 spin particles would not couple. I may be wrong on this issue.

There are nuclear isomers and excited bound states with energies in the keV to MeV above the ground state. If there is something nuclear going on, nuclear spin will no doubt be involved in the final account, if only because nuclear transitions have an initial and a final spin state. An attraction to focusing on nuclear spin is the possibility of fractionation of the energy of a large nuclear transition. For that to happen, you will want to have an explanation for why such transitions do not result in positron production or in penetrating photons from EM transitions. Eric
