Description

We report new results for the chemisorption system Ni (001)c(2 x 2)CO using angle-resolved polarization-dependent photoemission with synchrotron radiation (10 < or = hν < or = 40 eV). Adsorbate-induced structure with π-like symmetry is observed in normal emission at E/sub i/ approx. = -2.2 eV, and in the (100) mirror plane off normal at E/sub i/ approx. = -1.3 eV. Using the back-bonding scheme of Blyholder, an interpretation is given in terms of the mixing of metal dπ orbitals with the empty 2π orbital of molecular CO
