摘　　要：用全实加关联方法计算了类锂原子体系(Z=21～30)偶极跃迁1s22s-1s23p的跃迁能、振子强度以及1s23p态的精细结构劈裂。非相对论能量用Rayleigh Ritz变分法确定;相对论修正和质量极化效应用微扰论计算;同时考虑了来自量子电动力学(QED)效应的修正。得到的理论结果与实验数据及物理规律符合的很好。The transition energies and oscillator strengths of dipole transition 1s^22s-1s^23p for lithium-like systems with nuclear charge from Z=21 to 30 are calculated by using a full-core plus correlation (FCPC) method. The non-relativistic energies and wave functions are determined by Rayleigh-Ritz method. Relativistic and mass-polarization effects on the energies are calculated as the first-order perturbation corrections. The QED contributions to energy are also included. The fine structures of 1s^23p states for these ions are calculated by using spin-orbit and spin-other-orbit interactions operators. Our results are in agreement with experimental data available in the literature.
