Photon- and electron-stimulated desorption from a metal surface

Photon- and electron-stimulated desorption from a metal surface

Parallel measurements have been made on photon-stimulated and electron-stimulated desorption of F/sup +/, Cl/sup +/, and O/sup +/ ions from W(100). Ion energy distributions, angular distributions, and threshold yield behavior all indicate that the mechanisms for desorption by photons and electrons a...

Zusammenfassung:Parallel measurements have been made on photon-stimulated and electron-stimulated desorption of F/sup +/, Cl/sup +/, and O/sup +/ ions from W(100). Ion energy distributions, angular distributions, and threshold yield behavior all indicate that the mechanisms for desorption by photons and electrons are essentially identical. The extent to which the results are consistent with the core-level Auger model of Knotek and Feibelman is discussed.
