Semi-Relativistic Calcualations of Dielectronic Recombination for Ground -State Me-like Ge

  • 摘要: 采用半相对论多组态 Hartree-Fock 模型,计算了类 Ne 锗离子经过 3/3 l^\prime和 4/4 l^\prime 双激发态到类 Na 离子单激发态的态对态双电子复合速率系数 \alpha_m k^\mathrmDR,同时给出了描写上述复合过程的参数 B 和 \overline\Delta E。通过对 \alpha_m k^\mathrmDR 求和而获得的部分双电子复合速率系数与其它理论计算结果进行了比较。

     

    Abstract: Level-to-level dielectronic recombination (DR) rate coefficients for the \mathrmGe^22+ ion have been evaluated from the Ne -like ground state into the Na -like non-autoionizing states via the 3 l 3 l^\prime and 4 l 4 l^\prime manifolds. The fitted parameters describing this DR process are presented. The partial DR rate coefficients, obtained by summing level-to-level DR rate coefficients over the singly excited states of the \mathrmGe^21+ ion, are compared with available data. Our calculations are performed within the framework of the semi-relativistic multiconfigruation Hartree-Fock model, in which the relativistic mass-velocity and Darwin corrections are made to both the radial wavefunctions and the singly and doubly excited state energies.
