Extreme Ultraviolet Photoemission from Chromium Metal

Abstract

Photoelectron spectra of chromium metal have been measured in the excitation energy range from 30 to 80 eV at room temperature. Valence band spectra measured at low excitation energies are consistent with that of the calculated density-of-states curve in an overall feature, but not in a detailed feature. Resonant photoemission occurs in the valence band region on excitation above the 3p threshold. The general features of the intensity variations of valence band structures with excitation energy are consistent with the recent model calculation.
