A depolarization rate σ = 0.1205 ± 0.0050 μsec-1, due to the proton nuclear dipolar fields, was observed for polarized muons implanted in Pd-H0.97 in the β phase, at temperatures below 50 K, independent of temperature and applied field. The results indicate that the muon substitutes for one of the protons, and that nearest-neighbor protons are at octahedral lattice sites. On comparing our results with recent NMR data, it appears that the mean muon-proton nearest neighbor distance is significantly larger than that between protons alone. Also, a search for muon local moment magnetism gave a null result.
