The photoelectron spectra of the CuxNi1-x and AgxPd1-x alloy systems have been measured by means of a resonant photoemission technique to study the alloying effect on the valence band satellite. In the CuxNi1-x alloy system, the resonance intensity, which is defined as the area of the structure of the CIS of the 6 eV satellite normalized by Ni concentration, is found to increase with increasing Cu concentration. However, the difference intensity, which is defined as the difference between on- and off- resonance spectra normalized by Ni concentration, decreases with increasing Cu concentration. It is concluded that a valence electron transfer from the Ni 3d state to the Cu 4s state occurs upon alloying. This finding does not agree with the rigid band model, which explains the decrease in magnetic moment in terms of alloying. suggested that the in the Ni or Pd atomic site is a resonant state mixed with the neighboring valence hole state in the Cu or Ag atomic site.
