Energies, fine structures, and radiative lifetimes for the multiexcited quartet states of B-like oxygen

摘要

Energies for the multiexcited states 1s ~22s~2pnl and 1s ~22p ~2nl ~4P ~(e,o) (n ≥ 2) of B-like oxygen are calculated using Rayleigh-Ritz variation method with configuration interaction. The mass polarization and relativistic corrections are obtained with first-order perturbation theory. Configuration structures of the high-lying multiexcited series are identified by energies and contribution to normalization of angular-spin components. These structures are further checked by calculations of relativistic corrections and fine structure splittings. Hyperfine parameters and hyperfine coupling constants are calculated for the first time. Wavelengths including quantum electrodynamic effect and higher-order relativistic corrections and lifetimes are also calculated. These results are compared with available results in the literature.
