摘要 根据扩展的相对论多组态Dirac-Fock理论计算得到的Au47+~Au53+离子的平均离子寿命、能级能量和能级简并度,计算了各离子的电离速率常数、复合速率常数和配分函数,并由此得到了离子间的电离-复合平衡常数.基于这些数据,利用电离复合动力学方法研究了金等离子体内7离子系统在一定电子温度和电子密度下的电荷态分布和平均离化度.并给出了Au47+~Au53+的离子丰度与电子温度和电子密度的函数关系. The average lifetimes, the level energies and the level degeneracy of each gold ion from Au^47+ to Au^53+ have been calculated by the extended relativistic multi-configuration Dirac-Fock theory. Based on these data, the ionization rate constants, recombination rate constants, partition functions and ionization-recombination equilibrium constants of each ion have also been calculated. According to these calculated data, ionic charge state distribution and its average charge for 7 ion-system with electron temperature and electron density are reported using ionization-recombination dynamics method. Furthermore, the analytic functions to express the relations of ionic abundance with electron temperature and electron density are derived.
