Abstract
Quantum diffusion of positive muons has been studied in high purity Ta by zero and longitudinal field muon spin relaxation techniques. We found that the muon hopping rate in Ta is more or less the same as in pure Cu (i.e., \nu\simeq105\sim106\ s™1), showing a characteristic temperature dependence proportional to T™\alpha with \alpha ranging from 2 to 0.2 below 20 K. In addition, a step‐like change of the nuclear dipolar width was observed at 60 K associated with the sharp peak of hopping rate, suggesting a change of stable muon sites.

The trapping/detrapping leads to the change of effective dipolar width and thereby the fit by KT function always returns very poor results. For the lineshape, see K.G. Petzinger, Phys. Lett. A 75 (1980) 225.
