Energy Correlations in the ReactionBe9(d, tα)He4at 26.3 MeV

Abstract
The three-body reaction Be9+dt+α+α has been studied in a kinematically complete way at Ed=26.3 MeV. The data are represented in terms of projections for selected parts of the Dalitz plot, emphasizing the two-body resonance structure. Excitation energies and widths for the broad resonances are deduced. Although the reaction mechanism is shown to be predominantly sequential, we have observed a significant three-body breakup contribution (about 19% over the entire three-body phase space).
