摘要: 本文用相对论多组态Dirac-Fock广义平均能级（MCDF-EAL）模型,计算了可形成软x射线区相于辐射的类氟等离子体激光工作物质:Ce、Gd、Lu、Th、U类氟离子的2s²2p⁵、2s²2p⁴3l、2s2p⁵3l和2p⁶3l组态的113条能级,以及M亚壳层激发态至2s²2p⁵基态的²P_3/2,²P_1/2和2s2p⁶组态的²S_1/2态全部允许跃迁的强相干辐射波长值。

Abstract: In this paper, by using the relativistic multi-configuration Dirac-fock extended average level model, we calculate 113 levels of all the 2s²2p⁵、2s²2p⁴3l、2s2p⁵3l and 2p⁶3l configuration of lasing matter with the F-like type plasma,Ce,Gd, Lu, Th, U ions, which can produce coherent radiation feasibility of soft Xray, and results are prented for all allowed tranitory strong coherent radiation wavelength value from the singly excited M-subshell states to the tow-lying 2s²2p(²P_3/2,²P_1/2) configuration and 2s2p⁶(²S_1/2) configuration.
