用全实加关联方法计算了类锂Mn22+离子1s23d-1s2nf(4≤n≤9)的跃迁能和1s2nf(n≤9)态的精细结构.在类氢近似下估算了对能量的高阶相对论修正.依据量子亏损理论,确定了Rydberg系列1s2nf的量子数亏损.据此可以实现对任意高激发态(n≥10)的能量的可靠预言.计算了Mn22+离子1s23d-1s2nf(4≤n≤9)偶极跃迁的振子强度.

The transition energy of 1s^23d-1s^2nf（4≤ n ≤9） and fine structure splitting of 1s^2nf（ n≤49） states for lithium-like Mn^22＋ ion are calculated by using the full-core plus correlation method. The higher-order relativistic contribution to the energy is estimated under a hydrogenic approximation. The quantum defect of Rydberg series 1s^2nf is determined according to the quantum defect theory. The energies of any highly excited states with n≥10 for this series can be reliably predicted using the quantum defects which are function of energy. The dipole oscillator strengths for the 1s^23d-1s^2nf（ n≤9） transitions of Mn^22＋ ion are calculated with the energies and FCPC wave functions obtained above.
