The electronic state of oxygen adsorbed on a Cr(110) surface at 80 K has been studied by angle-resolved photoemission spectroscopy with synchrotron radiation. Dissociative chemisorption occurs up to 1/4 2 L, and then oxidation starts at 1/4 4 L, leading to the formation of a disordered Cr2O3 layer. An emission at 1/47.5 eV below the Fermi energy, being attributable to a chemisorbed O2 molecule, was observed at above 1/4 20 L. Dispersion effects on the O2pderived levels were found for the Cr(110)p(4×2)-O and faceted Cr(110)-O surfaces produced by annealing.
