Abstract

A proton NMR spin echo study of the system HfV₂H_x and ZrV₂H_x (0 ≤ x ≤ 4.5) hydrides are reported. The T₁ spin lattice relaxation rate enables us to extract the activation energy for diffusion, E_a, as well as the attempt frequency v₀; both depend strongly on the hydrogen concentration. The existence of a correlation between E_a and v₀ in these and other hydride systems yield the temperature dependence of the activation energy.
