摘　　要：用全实加关联方法计算了类锂Mn22+离子1s22s-1s2np(2≤n≤9)的偶极跃迁能和振子强度.1s2np(2≤n≤9)态的精细结构通过计算自旋-轨道与自旋-其他轨道相互作用算符的期待值确定.依据单通道量子亏损理论,确定了Rydberg系列1s2np的量子数亏损.从而可以用这些作为能量的缓变函数的量子亏损,实现对任意高激发态(n≥10)的能量的可靠预言.将这些分立态振子强度与单通道量子亏损理论相结合,得到在电离阈附近束缚态-束缚态跃迁振子强度以及束缚态-连续态跃迁的振子强度密度,从而将Mn22+离子的这一重要光谱特性的理论预言外推到整个能域.The dipole transition energy and oscillator strength for the 1s^22s-1s^2np（2≤n≤9） states of Mn^22＋ ion are calculated by using the full core plus correlation method.The fine structure splitting of 1s^2np（2≤n≤9） states are determined from the expectation values of spin-orbit and spin-other orbit interaction operators.The quantum defects this Rydberg series are determined according to the single channel 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.Combining the quantum defect theory with the discrete oscillator strengths,the discrete oscillator strengths for the transitions from the given initial state to highly excited states （n≥10） and the oscillator strengths density corresponding to the bound-free transitions are obtained.
