Spontaneous emission of a two-level atom from a dressed state in the quantized monochromatic radiation field

The process of creation of spontaneous photon in the 'atom+quantized monochromatic field' system is considered. The spectrum of emission consists of six lines, the intensities of which are essentially different in general. In the asymptotic strong fields only two lines remain, which correspond to the atomic transition and Rayleigh scattering. 25 refs
