Pavlenko Y. Properties of unbound and weakly bound states of light nuclei in external fields of accompanying particles

The thesis is devoted to determination of characteristics of light nuclei in processes that take place in the force fields of accompanying particles, specifically in the processes of break-up of weakly bound nuclei in the Coulomb field of heavy nuclei and decay of unbound nuclear states in the exit channels of many-particle reactions. The results of the study of 6Не+208Рb sub-barrier scattering indicate the existence of dineutron clusters in 6Не nucleus. The regularities of decay of 5,6Не, 5-7Li and 8Ве nuclear unbound states with different lifetime and excitation energy under condition of non-isolated decay in the Coulomb field of accompanying nuclei with different charge were determined in kinematically complete and incomplete experiments.
