COPPER L3-M4,5M4,5 AUGER AND AUGER SATELLITE STRUCTURES IN POLYCRYSTALLINE CU50PD50 ALLOY

The Cu L3M4,5M4,5 and Cu L8M4,5 - M4,5M4,5M4,5 Auger vacancy satellite spectra of polycrystalline Cu50Pd50 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 p hoton energies. The Auger and Auger vacancy satellite spectra of Cu in Cu50Pd50 are found to be identical to those of pure Cu. This result i s discussed in terms of the electronic structure of CuPd alloys.
