Three-body correlations in direct reactions: Example of ⁶Be populated in the (p, n) reaction

NUCLEAR REACTIONS ¹H(⁶Li, ⁶Be), E=47 MeV/nucleon; measured Eα, Iα, E(p), I(p), αp- and pp-coin, p(θ) and α(θ), differential σ(E) of channels populating g.s. and first 2+ state in ⁶Be, angular kinetic energy distributions of ⁶Be decay using two annular telescopes of position-sensitive silicon detectors with CsI(Tl) crystal arrays for particle detection using the U-400M cyclotron and ACCULINNA facility at the FLNR-JINR facility. ⁶Be; deduced integral invariant mass spectrum, density matrix spin structure for the 2+ state, energy distributions for the α+p+p decay of the ⁶Be continuum. Monte Carlo simulations. Relevance to high-statistics few-body correlation data to extract detailed information on the reaction mechanism.
