摘　　要：用全实加关联(FCPC)方法计算类锂离子体系(Z=11-20)1s2nd(n=6,7)态的非相对论能量。相对论及质量极化效应对能量的修正用微扰论计算,量子电动力学(QED)修正利用有效核电荷方法估算。在此基础上计算了1s23p-1s2nd(n=6,7)的跃迁能及振子强度,对现有的关于1s2nd(n=6,7)态的精细结构的实验数据的可靠性提出质疑。The 1s23p - 1s2nd(n =6,7) transition energies of lithium-like systems with nuclear charge from Z = 11 - 20 are calculated by using a full-core plus correlation (FCPC) method. The non-relativistic energies and wave functions are calculated by Rayleigh-Ritz's variation method. Relativistic and mass-polarization effects on the energies are included as the first-order perturbation corrections. The quantum-electrodynamics contributions to the transition energy are also evaluated by using effective nuclear charge. The results are in excellent agreement with experimental data in the literature. The dipole oscillator strengths 1s23p -1s2nd(n = 6,7) of these ions are calculated by using our FCPC wave functions.
