Abstract

Vibrations at a Ni(100) surface have been studied by Helium atom scattering. Adsorption of various adsorbates (CO,H,O) leads to characteristic changes and new features in the phonon spectrum of the clean surface. The dispersion curves for the clean substrate are compared to recent EELS data. Experimentally determined values for the frequency of the hindered translation of adsorbed CO-molecules strongly deviate from theoretical predictions.
