Relativistic multiconfiguration Dirac-Hartree-Fock calculations for energies, lifetimes, and E1, E2, M1, and M2 line strengths of Y XXXII

Abstract

Energies, wavelengths, line strengths, transition probabilities, and weighted oscillator strengths for electric dipole (E1), electric quadrupole (E2), magnetic dipole (M1), and magnetic quadrupole (M2) transitions among the levels arising from the n ≤ 3 configurations of oxygen-like yttrium, Y XXXII, are calculated using the multiconfiguration Dirac-Hartree-Fock (MCDHF) method. In the calculations, the valence-valence (VV) and core-valence (CV) correlations, as well as the Breit interaction (BI) and the leading quantum electrodynamics (QED) contributions are considered. Comparisons with the available results are used to determine the uncertainty for energies, wavelengths, and oscillator strengths. For lifetimes, E1, E2, M1, and M2 line strengths, the comparisons are also made between the two sets of the present MCDHF calculations to determine the accuracy of the results.
