Inner-shell processes of Li- and Be-like Fe

The core-excitation of inner-shell electrons incorporating the effects of radiation damping are investigated within a Breit-Pauli R -matrix framework. Highly ionized Fe species are known to undergo severe damping, both within the context of electron-impact excitation and photoionization. Hence, an n = 3 model of Li-like Fe is used to incorporate these effects on the resonance structure associated with the core-excited states produced by the electron-impact excitation of Li-like Fe and the photoionization of Be-like Fe. This work forms part of the RmaX Network, whose objectives include the study of inner-shell electron-impact excitation and photoionization processes, and is highly relevant to studies utilizing observations from the high-resolution x-ray satellites Chandra and XMM-Newton .
