Abstract
Muon spin relaxation in low (weak) longitudinal magnetic field (LLF-μSR) provides a means of independently determining the static dipolar width Δ characterizing the μ+ lattice site and the correlation time τc for μ+ hopping, in a manner that is nearly model-independent for τc and especially accurate in the near-static limit (τc>τμ). The advantages of this method are illustrated by its application to muon hopping in Cu near the τc maximum around 50 K.
