Electric dipole transitions between low-lying levels in doubly ionized krypton, xenon, and radon

Abstract

Using the general-purpose relativistic atomic structure package (GRASP) based on a fully relativistic multiconfiguration Dirac-Fock (MCDF) method, the transition parameters, such as transition rates (probabilities), oscillator strengths, and line strengths for the electric dipole transitions between low-lying levels are evaluated for doubly ionized krypton, xenon, and radon. Breit interactions for relativistic effects and quantum electrodynamical (QED) contributions besides valence and valence-core correlation effects are taken into account in calculations. We compare the results obtained with the available data in the literature and discuss them, when possible.
