Abstract
A proton NMR spin echo study of the system HfV2Hx and ZrV2Hx (0 ≤ x ≤ 4.5) hydrides are reported. The T1 spin lattice relaxation rate enables us to extract the activation energy for diffusion, Ea, as well as the attempt frequency v0; both depend strongly on the hydrogen concentration. The existence of a correlation between Ea and v0 in these and other hydride systems yield the temperature dependence of the activation energy.
