    Abstract

    The oxygen-induced Cu(110)-p(2 X 1)0 and Cu(110)-c(6 X 2)0 surfaces were studied by means of low-energy ion scattering combined with time of flight. The surfaces were bombarded with 6-keV Ar ions and azimuthal scans for recoiled 0 and Cu were compared with Monte Carlo computer simulations. The ''added row'' model for the p (2 X 1) structure is confirmed in this work. The oxygen atoms were found to be located in the [100] bridge position, 0.05 +/- 0.06 angstrom below the Cu atoms. The recently proposed structure for the c (6 X 2) surface was confirmed by our data and information about the z positions of the 0 and Cu atoms was obtained. The topmost ''superstructure'' Cu and 0 atoms are located 0.45 +/- 0.12 angstrom and 0.40 +/- 0.12 angstrom above the underlying Cu layer, respectively. The remaining 0 atoms are located in the 100 bridge positions 0. 12 +/- 0.12 angstrom below the Cu atoms.
