中文摘要：
基于多组态Dirac-Fock理论方法,利用GRASP92和RATIP以及在此基础上最新发展的RERR06程序,对类氢U^91＋（1s）离子的辐射复合截面以及辐射退激发过程进行了详细的理论研究.系统地计算了具有确定能量的连续电子被处于基态的类氢U^91＋（1s）离子俘获到nl（1≤n≤8,0≤l≤6）轨道形成类氦U^90＋（1snl）离子的辐射复合截面,并研究了这些辐射复合末态退激发谱的相对强度.研究发现,类氢U^91＋（1s）离子辐射复合到不同轨道的截面随其主量子数的增大而显著减小;同时,辐射复合末态的退激发对Kα谱线的相对强度有重要影响.
英文摘要：
Based on multi-configuration Dirac-Fock method,radiative recombination（RR）process of H-like uranium ion and radiative decay process of the resultant ion have been studied systematically using the recently developed program RERR06,which is based on GRASP92 and RATIP packages.In the studies,the RR cross sections from 1s state of H-like uranium ion to 1snl（1≤n≤8,0≤l≤6）of He-like uranium ion have been calculated in detail.Meanwhile,the relative intensity of the radiative decay spectra of the RR final states have also been studied.It was found that the RR cross sections to different orbitals decrease with the increasing of principal quantum number.Furthermore,an important contribution of the radiative decay of the RR final states to the relative intensity of Kα spectra has also been found in the present work.
