Contribution of the -core-excited states in determination of atomic properties in the promethium isoelectronic sequence

UI Safronova, AS Safronova, P Beiersdorfer - Physical Review A—Atomic …, 2013 - APS
The atomic properties of Pm-like ions were comprehensively studied using relativistic atomic
codes. Excitation energies of the 4 f 14 nl (with nl= 5 s, 6 s, 5 p, 6 p, 5 d, 6 d, and 5 f) states in …

Relativistic many-body calculations of excitation energies, oscillator strengths, transition rates, and lifetimes in samariumlike ions

UI Safronova, AS Safronova, P Beiersdorfer - Physical Review A—Atomic …, 2013 - APS
The unique atomic properties of samariumlike ions, not yet measured experimentally, are
theoretically predicted and studied in this paper. Excitation energies, oscillator strengths …
