Excitation energies, lifetimes, and transition data for Zr XXIX

Abstract

The energies and lifetimes of the lowest 303 fine-structure levels belonging to the 3s2, 3s3p, 3s3d, 3p3d, 3d2, 3snl (n = 4 − 6; l = 0 − 5), 3pnl (n = 4 − 5; l = 0 − 4), 3p6s, and 3dnl (n = 4 − 5; l = 0 − 4) configurations of Mg-like zirconium, Zr XXIX, are calculated using the relativistic multiconfiguration Dirac-Hartree-Fack (MCDHF) method employed in the GRASP2018 atomic structure computer package. The MCDHF wavelengths, transition probabilities, weighted oscillator strengths, and line strengths for the electric dipole (E1), electric quadrupole (E2), magnetic dipole (M1), and magnetic quadrupole (M2) transitions between the levels considered are presented. The Breit-interaciton (BI) and quantum electrodynamics (QED) effects are considered in the computations. Comparisons with available experimental and other theoretical data are carried out to evaluate the accuracy of the present results.
