摘要：

A theoretical analysis of the muon localization and delocalization in a superconductor with defects is presented. It is shown that suppression of inelastic scattering on the normal electron excitations results in a complete muon localization in a crystal volume or in the appearance (at low defect content) of free band motion regions. The depolarization rate has a remarkable nonmonotonic temperature dependence below T(c). The exponential increase of the depolarization rate starts with a significant shift from T(c) to the low-temperature region and the exponent has an unusual dependence on the muon-defect interaction potential.
