Copper L3-M4,5M4,5 Auger and Auger satellite structures in polycrystalline Cu50Pd50 alloy

Abstract The Cu L 3 M 4,5 M 4,5 and Cu L 3 M 4,5 - M 4,5 M 4,5 M 4,5 Auger vacancy satellite spectra of polycrystalline Cu 50 Pd 50 have been measured using tunable monochromatic x-rays from a synchrotron. The photon energy dependence of the Cu Auger satellite lineshape has been recorded for increasing photon energies. The Auger and Auger vacany satellite spectra of Cu in Cu 50 Pd 50 are found to be identical to those of pure Cu. This result is discussed in terms of the electronic structure of CuPd alloys.
