Abstract
Process of photon scattering on atoms is considered at energy above the ionization threshold. Influence of the resonant structure in the continuum, induced by a laser field due to coupling with the level 41S in helium, on the cross sections of elastic and inelastic scattering of a probe radiation on atom in the meta-stable state 21S is theoretically investigated. In the rotating wave approximation approach dependences of resonant scattering cross sections on the probe and laser radiation characteristics are obtained. The frequency and polarization dependences of the scattering cross sections to the final states of atom 11S, 21S and 41S are calculated.
