摘要
The local adsorption geometry of the low-coverage, short-range-ordered layer formed upon oxygen adsorption on the Rh(110) surface at 120 K has been quantitatively characterized by photoelectron diffraction measurements and multiple-scattering cluster calculations. The results of the structural analysis are compatible with a model where the oxygen atoms are located in the symmetric or slightly asymmetric short-bridge sites of the unreconstructed Rh(110) surface. O adsorption induces a small increase of the first substrate interlayer distance with respect to the relaxation of the clean Rh(110) surface.
