摘要：

A systematic series of ESCA measurements in Pt1-xCux manifest observable shifts for only the Cu core levels. These shifts are linearly related to the corresponding centroids of the valence band spectra. Physical arguments permit extraction of electronic valence structure changes induced by alloying from the measured quantities. Changes in Fermi energy are not related to differences in work function. The Pt valence structure appears unchanged and the Cu structure exhibits dehybridization. There is little charge transfer. © 1979.
