Cp. Lund et al., INTRINSIC SATELLITES IN THE L(23)VV AUGER-SPECTRA OF 3D TRANSITION-METALS, Physical review. B, Condensed matter, 49(16), 1994, pp. 11352-11357
Auger photoelectron coincidence spectroscopy (APECS) confirms that a s
ubstantial part of the low-energy tail of the L23 VV Auger lines of th
e 3d transition metals is due to intrinsic initial- and final-state sh
ake-up/shake-off processes and not just secondary losses. Data were co
llected for the L23 VV Auger lines of pure Cu, Co, and Ni. APECS enabl
es a direct experimental measurement of the initial-state shake-up/sha
ke-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.
