摘要
采用ＨＦ加相对论修正的ＨＦＲ方法，考虑束缚组态间的相互作用，计算了类氦铷与类氦铌离子各能级间跃迁的光电截面，所包括的离子组态为１ｓｎｌ—１ｓεｌ±１（１≤ｎ≤６、０≤ｌ≤ｎ－１），取自由电子能量区间为０～１０倍的离化能，分析了系统计算误差与计算精度，给出了对未态求和及三次样条插值后的结果。
Based on the HFR method for bound states and Distorted-Wave method for continuous states, photoionization cross sections that describe level to level transitions of He-like Rb and He-like Nb ions have been calculated.In the calculation,configuration interactions between bound states have been considered.The included configurations of the process are is nl→isεl±1(1≤n≤6,0≤l≤n-1),and the energy range of free electron is 0～10 times the ionization energy. The compututional error and the data accuracy are discussed.Also the results that have been summed over final states are provided.
