摘要：
The absolute values and the form of the cross section for two-photon one-electron excitation and ionization of the deep 2s shell of the Ar atom are calculated taking into account the many-body effects of relaxation of the atomic core in the fields of arising virtual vacancies and the decay of vacancies via the Auger and (or) radiative channels. The one-electron wave functions are calculated in the nonrelativistic approximation. The appearance of the Cooper minimum in the two-photon absorption cross section is established. The calculations are carried out for the linear and circular polarizations of photons of an incident laser beam. (C) 2002 MAIK "Nauka/Interperiodica".
