[en] Differential perturbed angular-distribution measurements have been performed for ¹⁰⁷Cd and ¹⁰⁹Cd in silver hosts. The data have been obtained at various target temperatures with and without applied magnetic fields. The theory of static, combined electric and magnetic hyperfine interaction has been applied for comparison of the zero-field quadrupole data and the external field Larmor-precession data. It is concluded that this combined interaction of the external magnetic field and the damage-induced, electric field gradients quantitatively accounts for the observed dependence of Larmor-precession amplitudes on time, temperature and field strength. The significance of the experimental time range for the appearance and thus for the interpretation of this dependence is demonstrated. (Auth.)
