Transition probabilities of the low-lying levels of Kr XXIV

Abstract

Energy levels, radiative rates, and wavelengths are calculated for all levels of 3s23p, 3s3p2, 3s23d, 3p3, 3s3p3d, 3p23d and 3s3d2 configurations of Al-like krypton ion (Kr XXIV). Multiconfigurational Dirac–Hartree–Fock (MCDHF) method is adopted for calculating energy levels and radiative rates. Transition probabilities are reported for E1 and M2 transitions from the ground level. The valence–valence and core–valence correlation effects are accounted for in a systematic way. Breit interactions and quantum electrodynamics effects are estimated in subsequent relativistic configuration interaction calculations. Comparisons are made with the available data in the literature and good agreement has been found which confirms the reliability of our results.
