Electronic structure and x-ray bands of CoSi2

Ab initio calculations of Si K, Si L, and do K x-ray emission and Si K and Co L absorption spectra (bands) were performed by means of all-electron pse udopotentials. In addition, the angular-projected local partial densities o f states at the cobalt and silicon sites were compared with the all-electro n full-potential linearized augmented-plane-wave results. All x-ray spectra are compared with available experiments, and good agree ment between ab in itio theory and experiment is found.
