A Theoretical Study of Spectral Line Intensities of the Helium Atom in an Alternating Circular Electric Field

Resumo

In this work, the behavior of the Stark component intensities of spectral lines in the emission spectrum of the helium atom excited by an alternating circularly polarized electric field is studied theoretically. The line intensities of an atom in the electric field are calculated within the framework of the method of energy matrix diagonalization. Based on the calculated results, a number of regularities have been revealed in the behavior of the Stark component intensities of the helium spectral lines with changes of the electric field strength.
