Abstract
It is suggested that a measurement of the temperature dependence of the most probableintensity of energy-resolved atom–surface scattering spectra can reveal the strength of thesurface corrugation. To support this conjecture, a classical mechanical theory ofatom scattering from a corrugated surface, valid in the weak corrugation limit,is developed. The general result for the scattering probability is expressed interms of spatial integrals over the impact parameter within a surface unit cell.For the case of a one-dimensional corrugation, approximate expressions for thescattering probability are obtained in terms of analytic closed form expressions. Asan indicator of its relation to experimental measurements, calculations using aone-dimensional corrugation model are compared with data for Ar scattering from amolten Ga surface and an approximate value of the corrugation height parameter isextracted.
