Regularities of the dynamic stark effect for an argon atom in a circularly polarized electric field

In this work, the Stark effect for an argon atom acted upon by an alternating circularly polarized electric field is studied theoretically. The calculations are carried out by the method of energy matrix diagonalization. The algorithm of the method is implemented using a special software package written in FORTRAN, which is used for computer simulation of shifts and splitting of the argon-atom states in the electric field. Based on the calculation results, regularities in the behavior of shifts and splitting of the energy levels of the argon atom depending on the electronic structure of the levels as well as on the changes in the strength and frequency of the electric field are derived.
