Abstract

Abstract A multiple-scattering analysis of LEED intensities has been made for the Rh(111)-(2 × 2)-O surface structure. The measurements were made with a video LEED analyser under conditions where the O layer disorders in 2 min in the incident electron beam. The experimental and calculated intensities were compared with Pendry's reliability index, which was minimised with O atoms adsorbed 1.23 Å above the “expected” hollow sites of three-fold coordination.
