Ultraviolet photoelectron spectroscopy of the valence bands of some Ag alloys

Abstract
Ultraviolet photoelectron spectra taken with 40.81 eV photons are presented for a series of AgSn alloys. The results are interpreted collectively with similar results previously obtained for a wide variety of Ag alloys and indicate that the width and splitting of the Ag 4d band are (i) independent of the second metal and (ii) strongly dependent on the mean number of nearest Ag neighbours.
