金等离子体中7离子系统(Au47+～Au53+)的电荷态分布及其解析函数关系

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.

Ionic charge state distribution of 7-ion-system(Au47+～Au53+) for gold plasma and its analytic functions

The average lifetimes,the level energies and the level degeneracy of each gold ion from Au47 to Au53 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.
