NON-LINEAR SUSCEPTIBILITIES AND ELECTROMAGNETIC TRANSITIONS IN FREE ATOMS TWO-ATOMIC SYSTEMS

By Vitaly Dmitrievich Ovsyannikov

Abstract

Processes of the non-linear interaction of electromagnetic fields with atoms, interatomic interactions in strong fields are investigated in the paper aiming at the theory construction for the interaction of atoms with some monochromatic fields, the determination of the influence of external fields on interatomic forces, the calculation of probabilities of multiquantum transitions at atomic collisions. As a result theory of disturbances for a quantum system in a field of some monochromatic waves has been constructed. The algorithm for the obtaining of analytical expressions for non-linear susceptibilities has been developed. The description of processes, induced by interatomic forces, with the help of two-atomic susceptibilities has been given. New data for the qualitative description of processes of the non-linear scattering, multiphoton ionization, laser-induced effects in interatomic interactions and collisional-induced electromagnetic transitions in atomar gases have been obtainedAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
