There were a large amount of work on the modernization of experimental equipment. Retrieved differential cross sections of elastic scattering processes deuterons in heavy nuclei (124Sn) at subbarrier energies Ed = 4 - 7.3 MeV), and held their theoretical interpretation to the specific structure of the incident deuterons. Experimental study of three-particle 7Li (d, aa) n, 7Li (d, ad) t and 7Li (d, ta) reactions in kinematics - full experiment which allowed to study the excitation spectrum of the nucleus 5He to excitation energies Ex ~ 40 MeV and install features settlement and the collapse of two - fragmented resonance (5He, 8Be). Obtained new experimental data on differential cross sections of elastic and inelastic scattering on the core 12C and the results of their analysis of the optical model and channels method at energies of deuterons 45,3 < Ed <60,6 MeV. Obtained new experimental data on elastic scattering on deuterons deuterons with energy Ed = 36,9MeV, deuterons on energy Triton at Ed = 27.4 MeV and alpha particles in at Triton Energy Ea = 84.2 MeV. Analysis angular distributions of elastically scattered deuterons 2,3H on nuclei at energies 12 <Ed <100 MeV under the quasi-classical approach allowed qualitatively explain the features of the structure and dt- dd- angular distributions. It is shown that the classical interference and diffraction significant amplitudes at energies Ed <37 MeV. Continued research processes splitting deuterons in the collision of a few nucleon systems. In the resulting energy and angular distributions of protons found that at low angles of departure proton splitting diffraction processes and processes of interaction in the final state, almost equally likely. With increasing angle of departure of protons prevails diffraction splitting process deuteron beam. The resulting energy spectrum of deuterons reaction 3H (a, d) at an energy of alpha - particle Ea = 84.2 MeV were qualitatively parameterized by taking into account two stepwise process of excitation and decay of resonant states of nuclei unrelated 5He * and 6Li *.     Lifght nucleus, nuclear reactions, cluster unstable nuclear states, at the threshold of nuclear resonance, the splitting of nuclei subbarrier interaction Product Description popup.authors .
