Experimental curves for the normalised azimuthal reflection difference Δr/r for clean and oxygen-reconstructed Cu(110) and Ag(110) between 1.5 and 5.5eV are presented. The copper spectra contain resonances at 2.1eV and around 4eV. Using expressions for the screened dipole-dipole interaction we have found that both the surface local-field effect and polarisation-dependent transitions between surface...
The Rh(110) surface was investigated using reflectance anisotropy spectroscopy (RAS). This optical method is shown to be sensitive to adsorbate-induced reconstructions of the Rh(110) metal surface. The reflection anisotropy can be used to monitor adsorption/desorption cycles of oxygen. The results are interpreted using the known substrate geometry of nitrogen-and oxygen-induced reconstructions of...
