Abstract
The time-dependent perturbation factors G2(t) of PAC are numerically calculated by diagonalizing the Blume’s supermatrix when static and fluctuating electric field-gradients are simultaneously present at the nucleus. The calculated functions are fitted with the expression of G2(t) given by isotropic models, strictly valid for asymptotic conditions. The asymptotic relations between the spin relaxation constant λ and the jump frequency w introduced in the stochastic model are found to be a good approximation in large domains of w values.
