Muon spin relaxation measurements (table 48) were performed on alloys which contained H, or which were H-free. It was found that there were marked differences between the activation energies, and the number of diffusion processes, which were identified in amorphous and crystalline samples. In crystalline samples, jump rates which were higher than 106/s were detected at about 90K. In amorphous samples, long-range diffusion began at a higher temperature. The results were essentially independent of the H content. Also, the diffusion processes for muons and H were very similar.
