利用多组态相互作用方法及Rayleigh Ritz变分法 ,计算了类铍BⅡ 1s2 2s2 1 S ,1s2 2s2p1 Po,1s2 2s2p3Po 和 1s2 2p2 3 P激发态的能量 .运用截断变分方法得到能量的改进量 .计算了相对论修正、质量极化效应 ,从而获得了高精度的能量计算值 .同时还计算了精细结构、辐射跃迁波长、振子强度、和辐射跃迁率 .计算结果与实验符合得很好 .

The Rayleigh-Ritz variational method is used with a multiconfiguration-interaction function and restricted variation method to obtain the energies of 1s 22s 2 1S, 1s 22s2p 1P o, 1s 22s2p 3P o and 1s 22p 2 3P in beryllium-like boron, including the mass polarization and relativistic corrections. Fine structure, oscillator strengths, transition rates and wavelengths are also calculated. The results are compared with other theoretical and experiment data in the literature.
