Abstract

It is shown conclusively that electron impact ionization of the C 1s and O 1s core levels of CO adsorbed on W(100) leads to CO+ and O+ desorption, respectively, and that soft-x-ray photons induce the same processes by an intrinsic photoeffect. Disintegration of the adsorption complex which becomes multiply charged by Auger decay of the core hole is assumed as explanation.
