Abstract

A theory for the interaction between electromagnetic radiation and a two-level atom in the electric- and magnetic-dipole approximation is presented. The Dyson-like equation satisfied by the propagators are generalized and a coupled set is obtained. This set is solved, and the susceptibilities are calculated. The dynamical equations for the fields are discussed when the field is supposed to be an unpolarized and isotropic field. It is remarked that the Lamb-shift is enlarged, and the line shape is enhanced. Near resonance the fields are comprised of resonant and off resonant parts. The reaction field is identified.
