Abstract: The processes of formation of stable and unstable states of 3-6He recoil nuclei in the exit channels of reactions 7,6Li(d, 3,4,6He) have been studied in kinematically complete and incomplete experiments at deuteron energy of 37 MeV. The excitation cross-sections of ground and the number of excited states of these nuclei have been determined. The possible mechanisms of continuum formation in inclusive spectra of 3,4,6He nuclei have been also studied. The probability of decay of resonance 5He*(16.75 MeV) into d + t channel in reaction 7Li(d, 4He)5He has been determined from the analysis of inclusive and exclusive experiments. Obtained data essentially differ from that obtained at the study of binary reactions.
