Abstract
We report on zero and transverse fieldμSR measurements in LaNi5H6 and inβ-PdHx (x=0.70 and 0.75) between 16 K and room temperature. Theμ +-depolarization is predominantly caused by the spread in nuclear dipole fields from the protons. Motional averaging is caused by the combined motion of protons and theμ +. The results are quite unexpected and point toμ +-trapping within regions of largely immobile hydrogen configurations or to a highly correlatedμ +-proton diffusion. In LaNi5H6 a linear change of the second moment with temperature between 20 K and 120 K is indicated.
