Abstract

The effect of the elastic fields of dislocations on γ‐ray perturbed angular correlations in paramagnets has been investigated. The γ‐ray directional correlations are perturbed by magnetic hyperfine and nuclear Zeeman interactions. The crystal imperfections cause the hyperfine splittings to vary from ion to ion. The frequency‐averaged perturbation factor taking into account these variations is obtained. For obtaining the frequency distributions a statistical method is used. Numerical calculations are performed for the case of the Er^3+^ion in CaF~2~.
