Publikováno v: Journal of Physics: Condensed Matter. 17:7029-7052

The MVV super Coster–Kronig (sCK) spectra of metallic Ni have been measured near the 3p excitation threshold by varying excitation photon energy. The results have been interpreted on the basis of the Cini–Sawatzky theory. The measured sCK band ha
