Krebs's model for noble metals and the screening parameter

Abstract

The specific heats of silver have been calculated on Krebs's model. These results have been discussed along with the earlier calculations on copper and gold published by one of us. It is found that Krebs's model is able to reproduce the experimental values remarkably well provided we consider the screening parameter as an adjustable constant. In the case of copper its numerical value is given by the theory of Bohm and Pines and for gold by that of Thomas and Fermi. For silver it lies between the two theories. © 1965.
