General regularities in the behavior of the rare gas spectra in alternating electric fields

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.
