The electronic structure of V(100) has been studied by means of synchrotron radiation. Normal emission (n.e.) spectra, taken in the energy range between 15 and 100 eV, were analysed in terms of existing band structure calculations. The obtained data support our previous reports suggesting that the peak at the Fermi level has a bulk and surface component. The variation of the intensity at the Fermi level was measured in the constant initial state (CIS) mode. In the photon energy range between 40 and 100 eV the variation of the intensity at the Fermi level is generally following the energy dependence of the resonant spectrum of vanadium films. However, the resonant spectrum obtained from V(100) appears to be significantly narrower than the spectra reported for films.
