The projected density of states (DOS) for the ground and excited states of boron in MgB2 has been calculated using the augmented plane wave plus local orbital method. The core-hole interaction is found to have a significant effect on the B pxpy states, but has little effect on the more metallic B pz states. The unoccupied B pxpy DOS near the Fermi level decreases as a function of core-hole strength. Comparisons with experimental electron energy loss spectra of the B K edge show that a simulation with half a core hole provides the best approximation to the final states in MgB2.
