Abstract
PulsedμSR spectra were measured with surfaceμ + in neutron irradiated aluminum as a function of specimen temperature above room temperature. It was found that the depolarization rate ofμ + increases and the precession frequency decreases as the specimen temperature is raised. This fact was attributed to the trapping ofμ + by radiation induced voids and suggests the importance ofμ +-surface interactions in the case of voids.
