Abstract
The processes of excitation and decay of high excited {sup 5}He resonances into the d + t channel have been studied in the three-particle channels of reaction {sup 7}Li(d, α){sup 5}He at the cyclotron U-240 of the Institute for Nuclear Research using the deuteron beam with energy E{sub d} = 37 MeV. In the inclusive spectra of α-particles on a significant background caused by the accompanying three-particle reaction channels, in addition to the contributions of well known {sup 5}He resonances the high excited states with E{sub x} ∼ 19 MeV and E{sub x} > 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 {sup 5}He resonances with E{sub x}≥22 MeV. The determined resonance energy and width are partially agreed with the R-matrix analysis of data obtained in the study of binary reactions d + {sup 3}H and n + {sup 4}He. The possible Coulomb effects in three-particle channels of reaction {sup 7}Li(d, α){sup 5}He are also analyzed for different conditions of observation of high excited {sup 5}He resonances.
