摘要

利用频率波动法(FFM)研究了离子热运动对等离子体中光谱线斯塔克展宽的影响。在 S. Chandrasekhar 和 J. von Neumann 随机理论的基础上,提出了一致计算跃迁频率(FFM 的主要参数)的方法。文中介绍了等离子体中性氢光谱的计算结果。这些结果与实验数据进行了比较。计算氘等离子体中掺杂氩的光谱时考虑了离子的热运动。显示了离子热运动对类氦氩离子的 Heβ 光谱线倾角的影响。类 He Ti 离子的 Heβ 线形计算结果与实验数据进行了比较。

Description of the Stark Broadening of Spectral Lines in Plasmas Taking into Account the Nonstationary Ion Microfield within the Theory of Markov Processes

The influence of ion thermal motion on the Stark broadening of spectral lines in plasmas is investigated within the frequency fluctuation method (FFM). The method for the consistent calculation of the jumping frequency, which is the main FFM parameter, is suggested on the basis of the S. Chandrasekhar and J. von Neumann stochastic theory. The calculations of the neutral hydrogen spectra in plasmas are presented. These results are compared with the experimental data. The spectra of the Ar dopant in the deuterium plasma are calculated taking into account ion thermal motion. The effect of ion thermal motion on the dip in the Heβ spectral line of the He-like Ar ion is shown. The calculations of the Heβ lineshape of the He-like Ti ion are compared with experimental data.
