Abstract
The 1s core-level excited spectra in LiF, BeO, cubic BN, CaB6, MgB2, SiC, diamond, and C3N4 were calculated using an ab initio pseudopotential plane wave method and a projector augmented wave reconstruction. Core-hole effects were investigated through a detailed examination of spectral differences between theoretical results from standard ground state calculations and from supercell calculations that included the core hole. A quantitative analysis reveals a relationship between core-hole strength and the valence charge population.
