Here is the cite for the original Hagelstein paper, ~ 24 years old:

There are different versions of neutron "hopping" these days, but in the
context of magnetic tunneling using NMR - as the medium to transfer
neutrons, and the most favorable reaction:
25Mg + 25Mg => 26Mg + 24Mg + 3.763 MeV
The idea is not to use hydrogen or deuterium at all, but to apply the
known NMR resonance to the metal, which is conductive so it can be
applied direct from a circuit. For instance, imagine a magnetic solenoid
in which a thin tube of magnesium isotope is held at cryogenic
temperatures which is oscillated at the NMR resonance, which would be
about 6 MHz for a magnetic field strength of 2.3 Tesla.
One application would be as a thruster for aerospace. Hot ions are
ejected from both ends of the tube when it is resonant along the axis of
the solenoid. One vector can provide thrust and the other converts the
ions to electricity to provide the resonance and cooling.
