Abstract
The relaxation of Pb 2+-vacancy and Cd 2+-vacancy dipoles in purified KCl crystals was studied using a double crystal dc polarization method which self-corrects relaxation effects due to spurious causes. In the radius range from Cd 2+ to Ba 2+ these results and most others support Dreyfus' model. The reciprocal relaxation times for each impurity are given by τ −1 Cd =2.06x10 12 exp(−s0.64±0.01 eV) kT ; τ −1 Pb =1.19x10 13 exp(−0.69±0.01 eV) kT . It is also shown that the presence of H 2O or its products greatly perturb the relaxation times observed.
