ResumoAbstract By means of low-energy ion scattering (LEIS), combined with time-of-flight (TOF) measurements, we studied the oxygen induced Ag(110)−c(6×2)O surface. The surface was bombarded with 6 keV Ar + ions. The coordinates of the O and Ag atoms were determined by comparing azimuthal scans for recoiled O with Monte Carlo computer simulations. The structure of the Ag(110)−c(6×2)O surface appears to be similar to the c(6×2)O phase of Cu(110). A general picture evolves in which both the p(2×1) ( O coverage = 1 2 monolayer ) and c(6×2) ( O coverage = 2 3 monolayer ) reconstructed surfaces of Ag(110) and Cu(110) exhibit the same geometric structure upon adsorption of oxygen.
