摘要：

Zero, longitudinal and transverse field mu SR measurements have been made on LiH, LiD and NaH. The primary motivation for the study was to elucidate the behaviour of the muons in the diamagnetic state and analysis of the time-dependent zero field relaxation data suggests that negatively charged muonium, Mu(-), is formed and takes up a H- vacancy site in these materials. Evidence is presented for a small (approximately 2%) reduction in the Mu(-)-Li distance relative to the unperturbed nearest neighbour anion-cation distances in the pure crystal lattices.
