对类ca钨离子的E1， M1， E2跃迁进行了全面的理论研究。利用有限主动空间处理的多组态diac - fock （MCDF）方法，计算了基态构型（[Ne]3s23p63d2）多态间M1和E2跃迁的波长和概率，以及[Ne]3s23p53d3和[Ne]3s23p63d2之间E1跃迁的波长和概率。所得结果与现有实验数据基本吻合。本文计算的E1和M1与以往的理论值进行了比较。对于E2跃迁，指出了3s和3p轨道电子相关的重要性。预测了几个强E1跃迁，这对等离子体诊断具有潜在的优势。
A comprehensive theoretical study of the E1, M1, E2 transitions of a Ca-like tungsten ion is presented. Using the multi-configuration Dirac–Fock (MCDF) method with a restricted active space treatment, the wavelengths and probabilities of the M1 and E2 transitions between the multiplets of the ground state configuration ([Ne]3s23p63d2) and of the E1 transitions between [Ne]3s23p53d3 and [Ne]3s23p63d2 have been calculated. The results are in reasonable agreement with available experimental data. The present E1 and M1 calculations are compared with previous theoretical values. For E2 transitions, the importance of electron correlation from 3s and 3p orbitals is pointed out. Several strong E1 transitions are predicted, which have potential advantages for plasma diagnostics.
