Angle-Resolved Photon-Stimulated Desorption of Oxygen Ions from a W(111) Surface

Abstract
A definitive determination of angle-resolved photon-stimulated desorption of ions from a well-characterized adsorbate, and a direct comparison with electron-stimulated desorption are reported. Ion angular distributions, energy distributions, and photon excitation spectra for O+ desorption from W(111) have been measured for oxygen coverages ranging from a fractional monolayer to a multilayer oxide.
