Abstract
Presents a study of the influence of correlations on the electronic optical excitations of transition metal surfaces. A Hubbard model in the band limit is solved by a second-order perturbation method previously developed for bulk metals. Excitation spectra of Mo(100) and Ni(100), (110) and (111) are shown to differ strongly from their respective one-electron local densities of states. This explains some features of experimental UV photoemission spectra of Mo.Keywords
