Transition probabilities for forbidden lines within the 4f² ground-state configuration of Pr IV

<b>Table 6.</b> Transition probabilities for forbidden lines within the 4f² ground-state configuration of Pr IV. <strong>Abstract</strong> Transition probabilities and oscillator strengths for electric dipole radiation in triply ionized praseodymium are reported for the first time in this paper. They were computed using a semi-empirical relativistic Hartree–Fock approach including core-polarization effects. Due to the lack of experimental data in the Pr IV spectrum, the accuracy of our results is estimated and discussed on the basis of comparisons between calculations performed with a similar physical model and laboratory measurements previously published for the isoelectronic ion Ce²⁺. In view of their great interest in optical materials and nanophotonics, radiative rates for forbidden lines within the 4f² ground-state configuration of Pr³⁺ were also calculated in our work.

表6. 三价镨离子（Pr IV）4f²基态组态内禁戒谱线的跃迁概率。**摘要** 本文首次报道了三价镨离子的电偶极辐射跃迁概率与振子强度，该结果通过包含芯极化效应的半经验相对论哈特里-福克（Hartree–Fock）方法计算得到。鉴于Pr IV光谱暂无实验数据，本文基于采用相似物理模型的计算结果，与已发表的等电子离子铈离子（Ce²+）的实验室测量值进行对比，对本研究结果的精度进行了评估与讨论。鉴于三价镨离子在光学材料与纳米光子学领域具有重要应用价值，本文同时计算了其4f²基态组态内禁戒谱线的辐射速率。
