The electronic structure of the ion-beam-mixed Pd-Au alloys have been studied using valence band spectra of XPS and electron excited CVV-Auger spectra. To show the relationship between the electronic structure changes and the Auger spectral line shape, the data of the self-convolution of the partially weighted valence band spectra was compared with the Auger spectra of Pd-Au alloys. The Pd-Au alloy is one of the systems which both atomic and band-like contributions are evident in the Auger spectral line shape. Since the self-convolution of PDOS's relates to the band-like part of Auger spectra, in Pd-Au alloys, the band-like structure in the Auger line shape can be classified by the self-convolution of the partially weighted valence band spectra. Finally, we found that the increase in peak size at ~80 eV with the increase in Pd content is due to the band-like contribution in the Au N 6 , 7 VV Auger line shape.
