摘要：

We report spectroscopic measurements of the azimuthal anisotropy in the normal incidence reflectivity of a clean and adsorbate-covered single-crystal metal surface: Reflectance anisotropy spectra were taken between 1.5 and 6 eV from Cu(110). On the clean surface, a sharp resonance is found which is assigned to a transition between two surface states at the (Y) over bar point of the surface Brillouin zone. The resonance can be removed by adsorption, and its energetic position is in good agreement with photoemission and inverse photoemission work.
