Abstract
The two available Mg 2p 1 core-level spectra of the recently discovered high-temperature superconducting MgB2 crystal exhibit interesting structures, but contradict each other. This motivated us to perform ab initio calculations on the core-level spectra of cluster models. The computed spectra reveal unusual rich and intense structures triggered by a B 2pz→Mg 3s,3p charge transfer.File in questo prodotto:
