Abstract

A considerable heat capacity anomaly of metals with unfilled d states at high temperature is explained using the Core Collapse Model (CCM). The XPS measurement of Pt atoms embedded in Cu matrix has been performed at different concentrations. The analogous measurement of Au atoms has been used as a reference. A difference in Pt levels’ behavior and their dramatic narrowing with diluting have been interpreted in favor of the CCM.
