摘　　要：用全实加关联方法计算类锂Ti+19离子1s22p～1s2nd(3≤n≤9)的跃迁能、振子强度和1s2np与1s2nd(n≤9)态的精细结构劈裂.得到的3种规范下振子强度的计算结果符合的很好,与已有的实验数据也相符合.确定了这2个Rydberg系列的量子数亏损.将上述分立态振子强度的计算结果与单通道量子亏损理论相结合,计算在电离阈附近(|E|≤I/2)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Ti+19离子量子跃迁特性的全能域理论预言.The transition energies and oscillator strengths of 1s^22p^1s^2nd (3 ≤n≤ 9) for lithium-like Ti^(+19) ion are calculated by using a full core plus correlation method. The fine structure splittings of 1s^2np and 1s^2nd(n≤9) states are also evaluated. The quantum defects of these two Rydberg series are determined. The values of oscillator strength obtained from three formulae 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 1s^22p state to highly excited states 1s^2nd(n≥10) and oscillator strength densities corresponding to the bound-free transitions are obtained for this ion.
