The interaction of He atoms with adsorbates placed on strongly corrugated substrates is investigated both theoretically and experimentally. An analysis of the scattering process within the transition matrix approach suggests that the normalized differential cross section, associated with the attenuation of coherent diffraction due to incoherent scattering in the presence of adsorbates, is expected to be largest for the most intense coherent diffraction peaks. For the adsorption of K on Cu(115), this trend is experimentally observed. {copyright} {ital 1996 The American Physical Society.}
