Rj. Cole et al., EXTRA-ATOMIC RELAXATION ENERGY CALCULATIONS USING AN EXTENDED POTENTIAL MODEL, Journal of electron spectroscopy and related phenomena, 72, 1995, pp. 255-259
We show how the ground state potential model used to analyse XPS shift
s can be extended to account for final state relaxation. The extended
potential model is found to describe rather well extra-atomic relaxati
on contributions to the XPS and Auger metal-atom shifts.
