Investigation of the oxygen chemisorption state in the p(2×2) and c(2×2) phases on Ni(100) with He scattering

Abstract

Analyses of He-diffraction data show that the oxygen adatoms produce well-separated corrugation hills with the same height and width in both the p(2×2) and c(2×2) phases on Ni(100). This confirms that oxygen chemisorbs in both phases in the same crystallographic and electronic configuration. The shape of the adatom corrugation requires a prolate charge distribution around each oxygen and should provide an important test as to the recently disputed electronic nature of the oxygen-substrate bond. © 1983 The American Physical Society.
