铝等离子体的平均离化度研究

Study on the Average Ionization State for Aluminum Plasma

利用基于多组态Dirac-Fock方程的程序包GRASP2K,详细计算铝离子各电离度的能级和跃迁,并通过求解速率方程,确定铝等离子体密度和温度下等离子体中离子的分布,给出不同密度下平均离化度随电子温度的变化关系.理论计算结果与实验值以及其它理论值符合很好,有助于分析已有的实验结果和指导拟开展的实验.

Using the package GRASP2 Kbased on the multi-configuration Dirac-Fock equation,the energy levels and transitions of each ionization degree of aluminum ions are calculated in detail.By solving the rate equation,the plasma ion concentration and the distribution of average ionization degree with electron density under different densities is given.The theoretical calculation results are in good agreement with the experimental values and other theoretical values,which can help to analyze the existing experimental results anddirect the future experiments.
