Abstract

Surface reflectance spectroscopy is used to determine optical transitions associated with the electronic structure of a W(100) surface during $H_{2}$ chemisorption. Correlation with photoemission and field-emission data attributes these transitions to excitations from intrinsic and adsorbate-induced levels to final states at the Fermi energy.
