Abstract
The diffusive motions of hydrogen in amorphous Zr2NiH2.5 were observed by 181Ta spin relaxation measurements with the perturbed angular correlation (PAC) technique. The temperature dependence of the spin relaxation constant corresponds to an activation energy significantly lower than in the crystallised hydride Zr2NiH3, but does not indicate the existence of a large distribution of hopping rates for the diffusion of hydrogen.
