Title: Photoemission for Xe Physisorbed on W(100): Evidence for Surface Crystal-Field Effects
Published: December 08, 1975
Abstract: Photoemission spectra at hv=21.2 eV reveal two 5p levels for xenon physisorbed on a tungsten (100) surface. The spin-orbit splitting of the two levels and their intensity ratio correspond closely to gas-phase measurements, while the 5p3/2 peak is significantly broadened with respect to the 5p1/2. We interpret the broadened structure as an unresolved doublet resulting from splitting the Xe 5p3/2 states in the tungsten-surface crystal field.
