Abstract
The occupied and unoccupied valence band states of MgB2 have been studied u sing high-resolution soft X-ray emission and soft X-ray absorption spectros copies. In particular, the B 2p partial density of states was measured near the Fermi level. The states at the Fermi edge are identified by comparison to calculation as being of B 2p(xy) origin. Resonant inelastic X-ray scatt ering indicates the existence of low-energy excitations at the B 1 s-edge a bsorption threshold.
