类氧Pr^（51＋）离子辐射跃迁几率和辐射寿命的GRASP计算

GRASP CALCULATION OF RADIATIVE TRANSITION PROBABILITIES AND RADIATIVE LIFETIMES FOR O-LIKE Pr￣(51+) ION

根据扩展的相对论多组态Ｄｉｒａｃ—Ｆｏｃｋ方法，使用我们新近开发的“多功能相对论原子结构程序（ＧＲＡＳＰ）”计算了类氧Ｐｒ５１＋离子的精细结构能级、跃迁波长、自发辐射跃迁几率、受激辐射跃迁几率、振子强度和辐射寿命。从计算结果中发现：在３ｐ－３ｓ跃迁中有１６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。这个结果与Ｅｌｔｏｎ［１］的预言进行了比较。

In this paper, according to expended relativistic multiconfiguration Dirac-fock code andusing ' a General- purpose Relativistic Atomic Structure Program (GRASP )', we havecalculated fine-structure energy levels, transition wavelengths, spontaneous radiative transitionprobabilities, stimulated radiative transition probabilities, oscillator strengths and radiativelifetimes for O-like Pr51+ ion. We can see from the results that there is great probility ofpopulation inversion and radiation XUV laser in 16 3p-3s transitions. The prediction is in goodagreement with Eltom's [1] and even more definite than his.
