Fig. 4: Angular correlations of breakup fragments 7Be and proton.
From: Breakup of the proton halo nucleus 8B near barrier energies
Comparison of experimental data (circles, with error bars indicating the associated statistical uncertainties) with simulations (squares) for correlations of β and θ12 at a 38.7 and d 46.1 MeV. The dashed curves show the expected β-θ12 correlation assuming asymptotic breakup from the 1+ resonance of 8B. The projections of β and θ12 at the corresponding energies are shown in b, c, and e, f, respectively, where the solid curves represent the simulations based on the CDCC calculations. The inset in a illustrates the definitions of β and θ12. The error bars show the associated statistical uncertainties.
