类氧铯离子激发态寿命和辐射跃迁几率的GRASP计算

GRASP Calculation of the Lifetime of Excited State and of the Emission Transition Probability in O-like Cs Ion

本文利用扩展的相对论多组态自洽场方法计算了类氧铯离子的精细结构能级、跃迁波长、激发态寿命、辐射跃迁几率和振子强度．从计算结果中发现：在３Ｐ，－３Ｓ跃迁中，有１９个跃迁的上、下能级间很有可能实现粒子数反转而辐射激光，特别是其中６个跃迁的可能性更大。

In this paper,using the expanded relativistic multiconfiguration Dirac-Fockcode, we have calculated the fine-structure energy levels, lifetime of excited state, wavelengths,emission probabilities,and oscillator strengths for electric dipole. magneticdipole, quadrupole transition in O-like Cs ion in both Coulomb gauge and Babushkingauge. We found from the results that there is great probability of radiation XUV laser inthe 19 3p-3s transitions, especially in the 6 transitions in the middle of them.The prediction is in good agreement with Elton's and even more definite than his.
