Abstract

The Au(110)-(1 × 2) reconstructed surface was studied by high energy ion scattering. Measurements of the He+ back scattering surface peak were made at 100 and 293 K as a function of energy (0.2 to 1.6 MeV) and crystal orientation. Comparison between measurements and calculations of the surface peak reveal that one monolayer of atoms is displaced in the surface plane by 0.12 ± 0.04 Å at 100 K and 0.18 ± 0.04 Å at 293 K. Assuming the missing row model, this corresponds to the second layer of atoms. Off-normal surface peak measurements give evidence for first layer displacements perpendicular to the surface.
