We use a soluble model of the decay of a 2+ particle into three identical strongly interacting 0+ particles to investigate the reaction 11B(p, α)2∝ at a proton energy of 2.65 MeV through the 18.37 MeV state of 12C. The strong final state interactions are described by Faddeev equations with separable two-body interactions to represent the ground and first excited states of 8Be. It is necessary to use a mixed 12C initial configuration to reproduce the experimentally observed interference effects. A fit to the data requires the approximate inclusion of the Coulomb phase shifts. The decay is dominated by final state interactions with little evidence for direct three-body decay.
