采用基于多组态Dirac-Hartree-Fock（MCDHF）方法的grasp 2 k程序包，对Al ix，Mn xxi，Fe xxii，Co xxiii，Ni xxiv，Cu xxv，Zn xxvi，Mo xxxviii，Au lxxv等电子序列沿着的2s{sup 2} 2 p-2s 2 p {sup 2}跃迁进行了广泛的组态相互作用计算.通过采用活动空间技术扩展组态列表，我们还包括Breit相互作用和量子电动力学（QED）效应，以校正原子态波函数和相应的能量。包括价相关和核心极化效应，后者是重要的长度和速度形式的振子强度的相关允许的过渡之间达成协议。精细结构能级，长期分裂，过渡能，过渡率，线强度，从而分支比与实验数据和其他计算值进行比较。
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.
