Abstract
Possibilities of the quasi-classical, Born, and semiclassical approximations for the description of the processes of bremsstrahlung, multiphoton ionization, and elastic and inelastic atomic collisions in the field of intensive laser radiation are considered. Large energy of electrons is a general characteristic for the specified processes in which ponderomotive interaction plays the important role. For processes with participation of slow electrons, proceeding near an ionization continuum border, the ponderomotive interaction has weak influence. Features of processes with participation of slow electrons and molecular ions in a strong light field, which proceed through a stage of intermediate Rydberg complex formation, are discussed. The main feature of these complexes is connected with the presence of the strong nonadiabatic connection of electronic and nuclear movement. For description of its display in various elementary processes, the perturbation theory is essentially inapplicable. The inverse problem in a possibility of restoration of the spectroscopic parameters entering into the theory of multichannel quantum defect is discussed.
