INNER CORE PHOTOELECTRON AND PHOTOABSORPTION SPECTRA IN METALS WITH INCOMPLETE SHELL

A model calculation of inner core photoelectron and photoabsorption spectra in transition metals is made by extending our previous theory such that incomplete shell states (d-state) construct a narrow energy band due to the transfer interaction among them and the hybridization with a conduction band. When a core electron is excited, the d-level of the excited atom is assumed to be lowered due to the core hole left behind. On account of this final state interaction, the photoelectron spectrum has a singular peak tailing off on the high energy side and a satellite, relative intensity of which depends sensitively on the banding effect of d-states. The density of states of the d-band is reflected in the photoabsorption spectrum, but due to the final state interaction it is highly deformed and remains only as a weak structure on the tail of a singular peak appearing at the threshold. © 1979, THE PHYSICAL SOCIETY OF JAPAN.
