VALENCE-BAND SPECTROSCOPY OF V(100) SURFACE

We have determined electron energy band dispersion of the vanadium val ence bands along the H-G-N high symmetry direction of the bulk Brillou in zone by use of angular-resolved photoemission spectroscopy of the V (100) surface. The dispersion of the states associated to the electron transitions from the bands G1 and G3 were found to be in very good ag reement with existing self-consistent electron band structure calculat ions for the bulk vanadium. Contrast to expectation, no surface state on the Fermi level has been proved.
