摘　　要：Hollow ion X-ray emission is of great interest in high-energy-density research,since negligible opacity allows studies from the interior of very dense objects.In this paper,ionization potential depressions of the isoelectronic sequences for single and double K-shell vacancies are obtained from a pure ab initio multiconfiguration Hartree-Fock simulation including exact exchange terms and finite temperature dense plasma effects.It is demonstrated that the simultaneous representation of these ab initio data in the form of a map of hollow ion X-ray transition energies enables identification of important steps in the matter evolution and ionization dynamics.Mapping along the isoelectronic sequence as a function of the pumping energy of a X-ray free electron laser also enables visualization of the impact of ionization potential depression on the pathways of hollow ion formation.
