An example of a metal that can hold a lot of hydrogen is palladium. The hydrogen atoms (protons) in the metal lattice are positive and the electrons are negative. When a large electric potential is applied across the lattice, the protons flux in one direction and the electrons in the other. Is it possible to increase the probability of electron capture (neutron production) by applying a large electric potential across a metal hydride, and if so at what potential/current? And what would be the effect of the lattice elements (e.g. palladium atoms) on this probability?
I would appreciate if anybody has suggestions about where I could find information on this subject.
