AbstractAbstract
[en] He-nozzle beams were scattered on a stepped Pt(997) surface. Diffraction peaks up to the 6th order are clearly resolved. For incident angles < 650, the diffraction patterns are very similar to the patterns obtained by light scattering on echelette gratings. An elementary model based upon this analogy fits the results fairly well. The deviations observed for glancing angles of incidence are interpreted as an evidence for an upward bending of the interaction potential on the terrace in the vicinity of the downward step. (Auth.)
