摘　　要：用全实加关联(FCPC)方法计算了类锂Zn27+离子1s2np(n≤9)态的精细结构.依据单通道量子亏损理论,确定了1s2nl(l=s,p)Rydberg系列的量子数亏损.用这些作为能量的缓变函数的量子亏损,可以实现对任意高激发态(n≤10)的能量的可靠预言.用在计算能量过程中确定的波函数,计算了Zn27+离子1s2ns-1s2np(n≤9)跃迁的振子强度,三种规范下的计算结果符合的很好.将分立态的振子强度结果与单通道量子亏损理论相结合,计算在电离阈附近分立态间的束缚态-束缚态跃迁振子强度与束缚态-连续态跃迁的振子强度密度,实现了具有较大核电荷数的类锂离子量子跃迁特性的全能域理论预言.The fine structure splittings of 1s^2np （n ≤ 9） states for lithium-like Zn^27＋ ion are calculated by using the full-core plus correlation （FCPC） method. The quantum defects of 1s^2nl （l=s,p） Rydberg series are determined according to the single-channel quantum defect theory. The energies of any highly excited states with n ≤ 10 for these series can be reliably predicted using the quantum defects which are function of energy. The dipole-length,-velocity and-acceleration absorption oscillator strengths for the 1s^2ns-1s^2np （n ≤ 9） transitions of Zn^27＋ ion are calculated with the energies and FCPC wave functions obtained above, the results obtained from three formula agree closely with each other.Combining the discrete oscillator strengths with the single channel quantum defect theory,the discrete oscillator strengths for the transitions from ls^22s state to highly excited states （n ≤ 10）and oscillator strength densities related to the bound-free transitions are obtained for the ion.
