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 41
S in helium, on the cross sections of elastic and inelastic scattering of a probe radiation on atom in the meta-stable state
21
S 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 11
S, 21
S and 41
S are calculated. |
