These processes play a significant, and in many cases a dominant role in shaping the final state of many channels of reactions with light nuclei.The report consists of abstract, four chapters and a list of references literature. The first two chapters are devoted to the experimental study of quasi-free processes and interactions in the final state occurring in the reactions D + D --> p + n + d and D + T -->t + n + p. Experimental data are given in the following sections obtained at accelerator U-240 INR NAS of Ukraine. Targets for research: D-Ti (titanium deuterium) and T-Ti (titanium tritium) self-supporting, made in INR NAS of Ukraine.  The first chapter is devoted to experimental study of the formation of deuterons in the reaction D + D --> p + n + d at energies Ed = 36.9 MeV and theoretical analysis of reactions at energies Ed = 36.9 MeV and 60, the second section - experimental research newts formation of three-particle reactions 3H (d, 3H) np with energy Ed= 36.9 MeV deuterons and analysis by modeling the spectra of Monte Carlo. Theoretical analysis of three-particle reactions splitting D + D --> p + n + d held by microscopic diffraction model that takes into account the interaction of nucleons in the final state and uses simple expressions for internal wave functions. Two type of three-particle reactions, nuclear fission to form multiple target deuteron and deuteron beam splitting to form a deuteron recoil. Satisfactory agreement of theory with experimental energy and angular distribution at = 36.9 MeV and 60 MeV achieved through the contribution of sections of two processes. Formation of tritons in the three-particle reaction 3H (d, 3H) np studied at the energy deuteronsEd = 36.9 MeV. Obtained new experimental data on triton energy distributions in the reaction 3H (d, 3H) np in a wide energy range of tritons. The shape of the spectra modeled considering kvazibinarni simple mechanisms and characteristics of experimental techniques for Monte Carlo. The structure of the spectra of tritium can not play, taking into account the processes quasi free scattering of protons and neutrons that make up the target in the incident deuteron and tritium nuclei interaction processes neutron and proton in the final state, and consistent collapse due to resonance 4H * (Ent = 2,2 MeV, Г= 3,4). The third section and fourth section describes the features of the experimental cinematically complete study of three-particle reactions 11B (p, aa)a and 7Li (d, aa)n protons at energies 2.65 MeV beam 3.75 MeV and beam deuterons with energy Ed = 4 2 MeV (the tandem generator EPG-10K INR NAS of Ukraine), respectively, and the results of the experiment.
