Abstract

Using x-ray excitation, the C(KVV) Auger spectrum for CO chemisorbed on Ni(100) has been measured and deconvolved to provide the undistored line shape. This line shape is compared with spectra for gas phase CO and Fe(CO) ₅(g). The magnitude of U_eff, a final state interaction term, is shown to be near zero for chemisorbed CO, indicating that significantly different relaxation/screening processes occur in this case as compared to gas phase CO and metal carbonyls. Charge-transfer screening of the core hole in the Auger initial state is proposed to account for the small value of U _eff.
