The optical properties of GaAs(110) and GaP(110) surfaces are studied by means of self-consistent local-density calculations. A very large contribution to the reflectance anisotropy is found to be related to transitions which do not involve surface states. These transitions give a substantialyet smallercontribution also to the differential reflectivity. Comparison is made with relevant experimental data.
