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