Abstract

The β-delayed charged particle emission from Li has been studied with emphasis on the three-body nαHe and five-body 2α3n channels from the 10.59 and 18.15 MeV states in Be. Monte Carlo simulations using an R-matrix formalism lead to the conclusion that the He resonance states play a significant role in the break-up of these states. The results exclude an earlier assumption of a phase-space description of the break-up process of the 18.15 MeV state. Evidence for extra sequential decay paths is found for both states.
