摘要：

By means of low-energy ion scattering (LEIS), combined with time-of-flight (TOF) measurements, we studied the oxygen induced Ag(110)-c(6 x 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 x 2)O surface appears to be similar to the c(6 x 2)O phase of Cu(110). A general picture evolves in which both the p(2 x 1) (O coverage = 1/2 monolayer) and c(6 x 2) (O coverage = 2/3 monolayer) reconstructed surfaces of Ag(110) and Cu(110) exhibit the same geometric structure upon adsorption of oxygen.
