Abstract
The first determination of two-dimensional adsorbate-induced corrugation functions from He-diffraction data is reported. Local maxima in the corrugations of both H(2×6) and H(2×1) on Ni(110) directly reflect adatom positions due to the localized charge distribution of the chemisorbed H atoms. Hence, genuine information on the adsorption sites is obtained leading to novel insight into coverage and adsorbate-adsorbate interactions. The transition to the reconstructed (1×2) saturation phase is discussed.Keywords
