溴到铷的类钠离子能级辐射跃迂几率和能级寿命

THE ENERGY LEVELS, RADIATIVE TRANSITION PROBABILITIES AND LEVEL LIFETIME FOR Na-LIKE Br TO Rb

本文在多组态Dirac-Fock(MCDF)理论框架下计算了水窗波段(λ:23.3～43.8A,相当于Z:34～46)的溴到铷的类钠离子1s^22s^22p^6nlj(n=3～15,l=0～6)各能级能量及各能级n_il_ij_i—n_kl_kj_k(n_i≤6,n_h≤15)间的电偶极辐射跃迁几率,并由此得出可能产生软X射线激光跃迁(4f-5g,4d-5f,4f-6g,4d-6f)的激光上能级的寿命,把计算得到的跃迁波长与实验测量值进行比较,其相对误差小于0.35％。

The energy levels and electric dipole radiative transition probabilities between levels niliji-nklkjk(ni≤6,nk≤15)for Br24+,Kr2c+,Rb26+ ions have been calculated. The lifetime of the candidate laser upper levels have been given.
