The core-level binding energy shift and L2,3 absorption-edges for pure Pd, Ag, and ion-beam-mixed Pd1-xAgx (x = 0.5-0.9) alloys are measured to investigate the charge redistribution in ion-beam-mixed PdAg alloys. It is found that, in ion-beam-mixed alloys, there is a substantial decrease in the area of the Pd L2,3 white lines compared with that of pure Pd. The observed decrease in white line area was attributed to an increase in the number of d-electrons at the Pd site upon alloy formation. Using the observed core-level binding energy shifts and white line area changes, the net charge transfer at the Pd site of ion-beam-mixed PdAg alloys has been estimated on the basis of a charge compensation model. We find that the net charge transfer is very small owing to back donation of sp-like conduction electron from the Pd site. These results are compared with the self-consistent electronic structure calculation.
