摘要
利用全实加关联方法得到的波函数计算类锂离子(Z=11-20)1s23d-1s2nf(4≤n≤9)的偶极跃迁振子强度,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(|E|≤I／2)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 dipole-length, -velocity and -acceleration absorption oscillator strengths for the 1s23d - 1s2nf (4≤n≤9) transitions of the lithium-like systems from Z=11 to 20 are calculated with the energies and the multiconfiguration interaction wave functions obtained from a full core plus correlation method. The results 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 1s23d state to highly excited states ( n≥10) and oscillator strength densities related to the bound-free transitions are obtained for these ions.
