V+20离子的能量和偶极振子强度

用全实加关联方法计算了类锂V+20离子 1s2nl(l=s,p, d;n≤9) 态的电离势和精细结构.依据单通道量子亏损理论, 确定了这三个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V+20离子1s22s-1s2np及1s22p-1s2nd (n≤9)跃迁的振子强度.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V+20离子的这一重要光谱特性的理论预言外推到整个能域.

Energy and dipole oscillator strength of V+20 ion

The ionization potentials and fine structure splittings of 1s~2nl(l=s, p, and d;n≤9) states for lithium-like V+20 ion are calculated by using the full-core plus correlation (FCPC) method. The quantum defects of these three 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 oscillator strengths for the 1s~22s-1s~2np and 1s~22p-1s~2nd (n≤9) transitions of V+20 ion are calculated with the energies and FCPC wave functions obtained above. 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.
