Effects of the atomic structure and interference oscillations in the electron photorecombination spectrum in a strong laser field

Electron photorecombination in the presence of a strong low-frequency laser field has been analyzed using an exactly solvable quantum model. It has been shown that interference patterns in the electron photorecombination spectrum are more sensitive to the details of the atomic potential than those in the case of other non-linear processes. For electron photorecombination on Xe$^+$ ions, the manifestation of the Ramsauer effect in the cross section for the elastic scattering of slow electrons on Xe$^+$ ions has been predicted in the electron photorecombination spectrum modified by the laser field.
