2020 7th International Congress on energy fluxes and radiation effects (EFRE 2020), Tomsk, Russia, September 14 – 26, 2020 : proceedings P. 387-392Abstract: A unified approach is developed for calculating profiles of spectral lines of atoms in an alternating electric field. This numerical method is based on diagonalization of the energy matrix of an atom in the electric field. To calculate the Stark profile of a spectral line, a formula is proposed, where the profile width contains an explicit dependence on the parameters of the electric field. The algorithm of the method is implemented in the software package StarkD written in FORTRAN and Maple. In the framework of the proposed approach, a computer simulation of the spectral lines of the helium atom in alternating electric fields of linear and circular polarizations is performed.
