Abstract

The behavior of the atomic emission spectra in alternating electric fields is studied in the unified theoretical approach based on numerical solution of the non-stationary Schrödinger equation. The developed approach implemented in the StarkD software package is free from limitations of perturbation theory. Based on the results of calculations, regularities in the behavior of the energy spectrum, the transition probabilities, and the intensities of the Stark components of the spectral lines of rare gas atoms He, Ne, Ar, and Kr have been established for the first time. These regularities make it possible to identify correctly the emission spectra in alternating electric fields. Additionally, the found regularities allow one to estimate the depletion rate of magnetic sublevels of atoms under changes in the electric field parameters, as well as to analyze the role of the electric field in the processes of quenching the atomic spectral lines and increasing their intensities. Practical applications of the obtained theoretical results are considered.

稀有气体谱在交变电场中行为的一般规律

在非平稳Schrödinger方程数值解的基础上，用统一的理论方法研究了交变电场中原子发射光谱的行为。在StarkD软件包中实现的开发方法不受摄动理论的限制。根据计算结果，首次建立了稀有气体原子He、Ne、Ar和Kr的能谱行为规律、跃迁概率和谱线Stark分量的强度。这些规律使得正确识别交变电场中的发射光谱成为可能。此外，所发现的规律还允许人们估计在电场参数变化下原子磁亚能级的耗尽率，以及分析电场在原子谱线猝灭和谱线强度增加过程中的作用。最后考虑了所得理论结果的实际应用。
