Abstract
We study the atomic reconstruction of the surface calculating electron-energy-loss (EEL) spectra and optical properties. The unreconstructed and three different atomic reconstructions are considered. We show that the optical properties are very sensitive to the atomic reconstruction. Results are presented and discussed in terms of differential EEL spectra that will allow to compare with experiments. Experiments are proposed to unambiguously determine the surface-atomic reconstruction of this important surface.
