Breit-Pauli energy levels, lifetimes and transition data: boron-like spectra

Breit-Pauli results for energy levels, lifetimes and some transition data are reported for all levels up to 2s2p( 3 P)3s 2 P J o of the B-like spectrum for 5⩽ Z ⩽14. For all but the lowest members of the sequence, these include the 2s 2 2p, 2s2p 2 , 2p 3 , 2s 2 3s, 2s 2 3p, and 2s 2 3d and 2s2p3s configurations, though only the 2s2p( 3 P)3s terms of the latter. A simultaneous optimization scheme was applied so that a radial basis could be determined for a set of terms that mix in the Breit-Pauli approximation. Convergence of the LS line strength is used as a factor in estimating accuracy as well as the agreement of energy levels and their splitting between theory and experiment. The results are evaluated by comparison with other theoretical results and experiment for transition rates.
