Abstract
Experimental curves for the normalised azimuthal reflection difference Δ r/ r for clean and oxygen-reconstructed Cu(110) and Ag(110) between 1.5 and 5.5 eV are presented. The copper spectra contain resonances at 2.1 eV and around 4 eV. Using expressions for the screened dipole–dipole interaction we have found that both the surface local-field effect and polarisation-dependent transitions between surface states at the Y ̄ point of the surface Brillouin zone are responsible for the main features in the spectra. In the silver spectra there is a resonance at 1.7 eV originating from polarisation-dependent transitions between surface states. The changes in the signals upon formation of ordered oxygen overlayers Cu(110)(2×1)-O and Ag(110)(2×1)-O are discussed.
