Electron Transfer in the Interaction of Fluorine and Hydrogen with Pd(100): The Case of a Transition Metal versus Jellium

Abstract

Results of a study of electron transfer processes in the interaction of fluorine and hydrogen with Pd(100), resulting in anion formation, are reported for a wide range of particle scattering conditions. We observe that the negative ion yield is much larger than what would be expected for a jelliumlike metal surface with a similar work function. These results indicate that capture occurs efficiently in the case of this very high work function surface and that the electron loss rates are much smaller than for the jelliumlike simple metal (e.g., aluminum) case.
