Abstract

The lifetime of the 1s² 2s² 2p²P_3/2 level as well as the fine structure energy splitting between ²P_3/2 and ²P_1/2 levels in the boron isoelectronic sequence for low to medium Z elements (Z = 14−36) and for selected high-Z elements (Z = 54, 64, 79, 82, 83, 92) have been calculated using the Dirac-Fock Multiconfiguration method with both quantum-electrodynamic and electronic correlation corrections included. All-order Breit and vacuum polarization corrections were included in the calculation, with a fully optimized active set wavefunction. The results are compared with other theoretical data, NIST database recommended values, and available experimental data. A good agreement with both theoretical and experimental values is obtained.
