The Ag M5N45N45 Auger photoelectron coincidence spectra of disordered Ag0.5Pd0.5 alloy

An effect of disorder broadening (DB) on the Ag M5N45N45 Auger spectra in the random substituted Ag0.5Pd0.5 has been investigated by Auger photoelectron coincidence spectroscopy (APECS). Data were collected for the Ag M5N45N45 Auger line coincident with the Ag 3d5/2 photoelectron line (and its higher and lower binding energy sides). It is shown that the broadening of the Ag M5N45N45 line is directly associated with the presence of disorder broadening of the Ag 3d5/2 photoelectron line. The APECS experiment is used to demonstrate the broadening in a novel way. [Copyright &y& Elsevier]
