Strong charge transfer effects in the Mg2p^{-1} core-level spectrum of MgB_2

N. V. Dobrodey, A. I. Streltsov, L. S. Cederbaum +2

The two available Mg2p^{-1} spectra of the recently discovered high-temperature superconducting MgB_2 crystal exhibit interesting structures, but contradict each other. This motiva…
