Anomalous behaviour 6 f the low-temperature heat capacity for KC 1 crystals with heavy univalent impurities

Abstract

The effect of low concentrations of heavy univalent Cs' and Iimpurities on the low-temperature heat capacity of KC1 gives an enhancement in the heat capacity. This anomalous behaviour has been explained on the basis of a low concentration Green's function theory. A localized perturbation model which includes mass change at the impurity site as well as… (More)
