Extensive configuration interaction calculations for the 2s{sup 2}2p-2s2p{sup 2} transitions for several ions along the B I isoelectronic sequence (Al ix, Mn xxi, Fe xxii, Co xxiii, Ni xxiv, Cu xxv, Zn xxvi, Mo xxxviii, and Au lxxv) have been calculated using the grasp2 k package based on the multiconfiguration Dirac-Hartree-Fock (MCDHF) method. By employing active-space techniques to expand the configuration list, we also included Breit interaction and quantum electrodynamical (QED) effects to correct atomic state wave functions and the corresponding energies. Both valence correlation and core polarization effects are included, the latter being significant in achieving agreement between length and velocity forms of the oscillator strengths of related allowed transitions. The fine-structure energy levels, term splitting, transition energies, transition rates, line strengths, and thereby the branching ratios are compared with experimental data and with values from other calculations.
