Abstract

The electronic structure of the V(100) surface has been studied by means of angularly resolved photoelectron spectroscopy (ARUPS) and momentum- ( k -) resolved inverse photoemission spectroscopy (KRIPES). A narrow peak in the photoemission spectrum which is seen at the Fermi level is attributed to a transition from a surface resonance. The existence of this surface resonance at the Fermi level of the V(100) surface is potentially very important for the occurrence of the expected magnetic ordering of this surface. The energy of the critical point , which defines the top of the unoccupied part of the 3d band, has been determined to be within 3.0 - 3.2 eV above from the normal incidence KRIPES spectra.
