Nuclear and Coulomb Interaction in 8B Breakup at Sub-Coulomb Energies

Abstract

The angular distribution for the breakup of 8B→7Be+p on a 58Ni target has been measured at an incident energy of 25.75 MeV. The data are inconsistent with first-order theories but are remarkably well described by calculations including higher-order effects. The comparison with theory illustrates the importance of the inclusion of the exotic proton halo structure of 8B in accounting for the data. © 2000 The American Physical Society.
