| Popis: | Several parameters (cross section, reaction rate, etc.) of various processes in laser, atomic, and chemical physics are calculated using quantum scattering theory for a system of a few particles. Results of the study of electronic and atomic collisions with diatomic molecules and collisions of diatomic molecules in excited rovibrational states are discussed. Several approximations needed for calculations of real physical systems consisting of several bodies are analyzed. Such approximations can be used for simulation of direct reactions and reactions that yield intermediate transient complexes. Calculated cross sections of electronic and atomic collisions with diatomic molecules and collisions of diatomic molecules are compared with experimental data and results of alternative calculations. |
