Abstract

The BPP model for nuclear spin relaxation is modified to accountrigorously for jumps of hydrogen within g site hexagons in the C15 AB2 structure. The theory is applied to proton relaxation data for low H concentrations in TaV₂Hx and ZrCr₂Hx. It is shown that the data is consistent with the results of quantum diffusion calculations, diffusivity measurements, and H-H interaction effects deduced from quasielastic neutron scattering experiments.
