Energies and electric dipole transitions for triply ionized Kr, Xe and Rn

New Transition and Energy Levels of Three-Times Ionized Krypton (Kr IV)

“…Reliable values of oscillator strengths, transition probabilities, and radiative lifetimes of energy levels are essential for the study of the ionized noble gases in Kr IV [9]; also, for astrophysical applications, for example, calculating Kr IV-VII oscillator strengths to consider radiative and collisional bound-bound transitions in detail in the non-LTE stellaratmosphere models for the analysis of Kr lines that are exhibited in high resolution and high S/N ultraviolet (UV) observations of the hot white dwarf RE0503289 [13]. Recently energies and transition parameters have been reported for triply ionized Kr IV, Xe IV, and Rn IV using the general-purpose relativistic atomic structure package based on a fully relativistic multiconfiguration Dirac-Fock method [14]. In this article, we present an extension of the analysis of Kr IV from reference [2], including five energy levels of the configuration 3s 2 3p 2 4d and twenty levels of the 3s 2 3p 2 5d configuration.…”
