Deuteron and triton decays of 5He resonances in the reaction 7Li(d, α)5H

The processes of excitation and decay of high excited 5He resonances into the d + t channel have been studied in the reaction 7Li(d, α)5He* at the energy of deuteron beam Ed = 37 MeV. In the inclusive spectra of α-particles in addition to the contributions of well known 5He resonances, the high exci...

Description
Summary:The processes of excitation and decay of high excited 5He resonances into the d + t channel have been studied in the reaction 7Li(d, α)5He* at the energy of deuteron beam Ed = 37 MeV. In the inclusive spectra of α-particles in addition to the contributions of well known 5He resonances, the high excited states with excitation energies Ex ~ 19 and Ex > 20 MeV were observed. Cluster decay of these resonances was also identified in αd- and αt-coincidence spectra. For the first time, the decay into the d + t channel was observed for 5He resonances with Ex = 22 and 26 MeV. The determined resonance energy and width are partly agreed with the R-matrix analysis of data obtained at the study of d + 3H and n + 4He binary reactions. The possible Coulomb effects in three-particle channels of reaction 7Li(d, α)5He* are also analyzed for different conditions of observation of high excited 5He resonances.
