摘要：

We have investigated the composition and structure of the outermost two layers of the Cu85Pd15(110) (2 x 1) surface using low-energy ion scattering. Time-of-flight forward scattering and recoiling measurements show that the surface is unreconstructed. From the energy and azimuthal distributions of backscattered 2 keV Ne+ ions as obtained with the EARISS (energy and angular resolved ion scattering spectrometer) it is concluded that the first layer is possibly depleted in Pd whereas the second layer is strongly enriched. These results are in agreement with a previously proposed model for the surface based on LEED, angle resolved XPS and TPD measurements.
