We report the structure of the (1×2) reconstruction induced by 0.1 monolayer of Ca atoms on the Au(113) surface, using medium-energy ion scattering. Our data show that the (1×2) surface corresponds to a missing-row-type reconstruction. Monte Carlo simulations of the experiment provide a quantitative measurement of the atomic positions at the surface. All the displacements in the surface region are such that the resulting structure smooths out the corrugation inherent in a missing-row reconstruction. We discuss the relation between this reconstruction and the energy balance between competing surface-electronic-charge densities. © 1992 The American Physical Society.
