我们对使用电子束离子阱观察到的光谱中先前未识别的可见线进行了研究。该分析基于具有精细结构亚级群体动力学的碰撞辐射 (CR) 模型。为了确保 CR 模型完成的线识别，我们还使用grasp2018 对多构型 Dirac-Fock 方法中的跃迁能量和跃迁概率进行了准确计算。在光谱中，大多数观察到的线被指定为属于这些离子的前两个较低位置配置的磁偶极子跃迁。
We present an investigation of previously unidentified visible lines forandfrom the spectra observed using an electron-beam ion trap. The analysis is based on collisional-radiative (CR) modeling with fine-structure sublevel population kinetics. To ensure the identification of lines done by the CR model, we have also performed an accurate calculation of transition energies and transition probabilities within the multiconfigurational Dirac-Fock approach usinggrasp2018. In the spectrum, most of the observed lines are assigned as magnetic dipole transitions belonging to the first two lower-lying configurations of these ions.
