THEORY OF NEGATIVE ION FORMATION IN CO CHEMISORBED ON NI(110) - THE (2)SIGMA SHAPE RESONANCE

摘要

The lifetime, energy and angular distributions for resonance electron scattering by the (2) Sigma Shape resonance of CO chemisorbed on Ni(110) are calculated using a layer-KKR method. This calculation is based upon a multiple scattering approach to negative ion formation at surfaces in which the substrate scattering is fully incorporated. The results are compared to the experimental study of Jones et al. Chem. Phys. Lett. 161 (1989) 467 and a prior coupled-angular-modes (CAM) study by Teillet-Billy and coworkers that considered only the screening of the negative ion by the metallic substrate Nucl. Instrum.
