摘要
利用基于多组态Dirac-Hartree-Fock方法的程序包GRASP2K,考虑电子关联作用,详细计算Ti的类Al离子3s 23p和3s3p 2 的能级、波长以及跃迁特性.研究表明,考虑电子关联作用之后,所得的计算结果与实验值符合得更好.计算结果对于分析现有的实验结果和帮助标定未来实验产生的谱线有重要的意义.
We present a comprehensive theoretical study of atomic characteristic of Ti X in a broad range of wavelengths, energy levels and transition probabilities. The results calculated by multiconfiguration Dirac-Fock (MCDF) and relativistic configuration interaction calculations (RCI) including the Breit interaction are presented. The valencevalence and core-valence correlations are also considered. The calculated values including core-valence correlation are found to be similar and to compare very well with other theoretical and experimental values. We believe that our extensive calculated values can guide experimentalists in identifying the fine structure levels in their future work.
