Abstract:

A new method is proposed for calculation of the dynamic Stark effect in a circularly polarized electric field of arbitrary frequency and intensity. The basic equations of the method are presented. In the framework of the approach proposed, shifts and splits of energy levels for the He atom in the circularly polarized electric field are calculated.
