Mg IX原子在等离子体参数下的跃迁理论研究
|
Abstract:
本文采用基于全相对论多组态狄Dirac-Fock波函数的GRASP92程序包,对Mg IX的原子参数展开了全面、详细的光谱研究与分析。文中给出Mg IX的能级、跃迁辐射数据以及量子动力学的影响,所得结果与其他理论结果符合较好。本文还阐释了高温稠密等离子体的表征方法,给出了其温度、电子密度、趋肤深度、等离子体频率等关键参数。研究认为,所得数据可为后续的光谱线对比与识别、等离子体建模以及聚变和天体物理等离子体研究提供重要参考。
In this work, a comprehensive and detailed spectroscopic investigation and analysis of the atomic parameters of Mg IX were carried out using the GRASP92 package based on fully relativistic multi-configurational Dirac-Fock wave functions. The energy levels, radiative transition data of Mg IX and the effects of quantum electrodynamics are presented herein, and the obtained results are in good agreement with other theoretical results. In addition, the characterization method of hot dense plasma is illustrated, with its key parameters including temperature, electron density, skin depth and plasma frequency provided. It is believed that the obtained data can serve as an important reference for the subsequent comparison and identification of spectral lines, plasma modeling, as well as research on fusion and astrophysical plasma.
