Abstract: At deuteron energy of 37 MeV the ⁶He inclusive spectra are measured in the exit channel of reaction ⁷Li(d,⁶He)³He. The resonance-like structure of spectra in the range of ⁶He energies corresponding to the excitation of ³He recoil nuclei in the range of E* = 6…16 MeV was observed. The experimental data can be described in assumption of existence of ³He resonances with excitation energies of Е* = 9, 13 and 16 МеV. An analysis of the experimental spectra shows that observed structure of ⁶He spectra can be as well explained by the more probable processes of excitation and decay of ⁷Li and ⁷He unbound states in accompanied reaction channels.
