Calculations of three-body observables in 8B breakup

Abstract

We discuss calculations of three-body observables for the breakup of 8B on a 58Ni target at low energy using the coupled discretized continuum channels approach. Calculations of both the angular distribution of the 7Be fragments and their energy distributions are compared with those measured at several laboratory angles. In these observables there is interference between the breakup amplitudes from different spin-parity excitations of the projectile. The resulting angle and the energy distributions reveal the importance of the higher-order continuum state couplings for an understanding of the measurements.
