Abstract

We report numerical computations of the PAC perturbation factor G2(1) for spin 5/2 nuclei subject to a static EFG symmetric about the z-axis and an additional axially-symmetric EFG whose symmetry axis fluctuates randomly among the x, y, z directions. For sufficiently large fluctuation rates, the numerical results are described by the expression for the static interaction alone with the addition of relaxation terms. Results of applying this model to111Cd TDPAC measurements on tetragonal ZrO2 are described briefly. The model allows one to evaluate the probability that oxygen vacancies are trapped. the energy of association of vacancy-metal pairs, and the vacancy activation energy of motion.
