X-ray transition and K-edge energies in dense finite-temperature plasmas: Challenges of a generalized approach with spectroscopic precision
Fig. 1. Schematic illustration of valence-band-like features with bound and free states in the framework of an ion-sphere model (
Fig. 2. Schematic illustration of core-hole vacancies production in the framework of the VB-BFC valence band model. Case (a) depicts Al I with 13 bound electrons corresponding to the excitation of a K-electron, while case (b) shows Al II with 12 bound electrons and one free electron corresponding to the ionization of a K-electron.
