Description
Guided control of molecular processes and creation of the new molecular structure is a subject of active research in molecular and chemical physics. One of the most natural and general approaches in this area is a quantum few-body theory based on the Faddeev-Yakubovsky equations [1,2]. It is based on the idea, that the possible mechanisms of occurrence of chemical reactions based on a specific multiparticle interaction under condition of low coupling energy between clasters of the system.
Investigation of the methods and tools for creation of the new molecular structures with new properties and control of chemical reaction on the base quantum theory of few-body system are presented. A general method for study three-body recombination reactions base on Faddeev-Yakubovsky equations is developed. Calculations of the three-body recombination rate of the reactions [2-5] H + H + H → H 2 +H, He+He+He → He 2 +He,Cs + +Dr − R → CsBr + R for low energies are compere with classical results and other approximations.
