Abstract

Auger photoelectron coincidence spectroscopy (APECS) confirms that a substantial part of the low-energy tail of the L23VV Auger lines of the 3d transition metals is due to intrinsic initial- and final-state shake-up/shake-off processes and not just secondary losses. Data were collected for the L23VV Auger lines of pure Cu, Co, and Ni. APECS enables a direct experimental measurement of the initial-state shake-up/shake-off satellites in solid-state Auger spectroscopy. The importance of these effects in Auger spectroscopy as a qualitative and quantitative surface-analysis technique is discussed.
