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.

Core Correlation

In this paper two different approaches are used to study core correlation effects in the 3p64s4p I pO state of calcium. We show that the number of relevant configurational functions in the configuration interaction expansion can be reduced by determining the core correlation functions prior to the valence correlation functions. We also show that core correlation effects of the form 3p2 ~ nP can be represented in the configuration interaction expansion by including configurational functions of the type 3p4(S L) nP(S L){ IS 14s4p in the expansion.
