采用基于多组态Dirac-Hartree-Fock（MCDHF）方法的GRASP 2K程序包，计算了18 <$Z <$92类B离子2 p3和2s 22 p奇组态间的双电子单光子（TEOP）M1和E2跃迁能、谱线强度和跃迁几率.利用活性空间技术扩展了组态表，系统地考虑了原子价、核-价和核-核电子关联效应。此外，还考虑了Breit相互作用和量子电动力学（QED）效应来修正原子态波函数和相应的能量。详细分析了电子关联、Breit相互作用和QED效应对TEOP M1和E2跃迁能量和谱线强度的影响。本文的结果还与其他理论和实验值进行了比较。
Two-electron–one-photon (TEOP) M1 and E2 transition energies, line strengths and transition probabilities between the states of the 2p3 and 2s22p odd configurations for B-like ions with 18 ⩽ Z ⩽ 92 have been calculated using the GRASP2K package based on the multiconfiguration Dirac–Hartree–Fock (MCDHF) method. Employing active-space techniques to expand the configuration list, we have systematically considered the valence, core–valence and core–core electron correlation effects. Breit interaction and quantum electrodynamical (QED) effects were also included to correct atomic state wavefunctions and the corresponding energies. Influences of electron correlation, Breit interaction and QED effects on transition energies and line strengths of the TEOP M1 and E2 transitions were analysed in detail. The present results were also compared with other theoretical and experimental values.
