Abstract
The multiconfiguration Dirac-Hartree-Fock (MCDHF) method is used to calculate energies, lifetimes, wavelengths, transition probabilities, weighted oscillator strengths, and line strengths for electric dipole (E1), magnetic dipole (M1), electric quadrupole (E2), and magnetic quadrupole (M2) transitions among the lowest 226 fine-structure levels arising from the 2s22p4, 2s2p5, 2p6, 2s22p33l, 2s2p43l, and 2p53l (l = s, p, d) configurations in O-like Nb XXXIV. The valence and core-valence correlation effects are included in the calculations. The Breit-interaction and the leading quantum electrodynamics contributions are taken into account in the relativistic configuration interaction calculations. The present energies, wavelengths, line strengths, and oscillator strengths are compared with the available experimental and other theoretical results. The accuracy of the present results is estimated using the comparison between the results from the two largest layers in the present MCDHF calculations.
