Calculating Spectral Characteristics of the Helium Atom Excited by an Electric Field in Plasma of Current Sheets

In this work, the behavior of the energy spectrum and probabilities of transitions between the Stark states are studied theoretically for the helium spectrum emitted by plasma of current sheets. Calculations are performed by the method of the energy matrix diagonalization of an atom in the electric field. The results obtained have allowed us to reveal a number of regularities in the behavior of shifts and splitting of atomic levels and transition probabilities for the emission spectrum of the helium atom in a circularly polarized electric field arising in plasma of current sheets.
