Abstract

Simulations of perturbed angular correlation (PAC) spectra were carried out to investigate the effects of nonequilibrium distributions of PAC probes. The XYZ model with a trapping-detrapping mechanism was chosen to represent a system in which point defects are trapped by, detrap from, and hop around PAC probes. Calculations were based on the method of Winkler and Gerdau.
