V^(20+)离子1s^23d-1s^2nf的跃迁能和振子强度

Transition energy and dipole oscillator strength for 1s^23d-1s^2nf of V^(20+) ion

用全实加关联方法计算了类锂V20+离子1s23d-1s2nf的跃迁能和偶极振子强度.依据量子亏损理论,确定了1s2nf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,实现对该Rydberg系列任意高激发态(n≥10)的能量的可靠预言.将这些分立态振子强度与量子亏损理论相结合,得到在电离域附近束缚态间的偶极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V20+离子的这一重要光谱特性的理论预言外推到整个能域.

The transition energies and the dipole oscillator for 1s^23d-1 s^2nf states of lithium-like V^20＋ ion are calculated by using the full-core plus correlation （FCPC） method. The quantum defect of 1s^2nf series is determined according to the single-channel quantum defect theory. The energies of any highly excited states with n≥10 for this Rydberg series can be reliably predicted,using the quantum defects which are function of energy. Combining the quantum defect theory with the discrete oscillator strengths in this work, the behavior of discrete oscillator strengths and oscillator strengths density corresponding to the bound-free transitions are obtained.
