Nuclear interference effects in 8B sub-Coulomb breakup

The breakup of B-8 On Ni-58 below the Coulomb barrier was measured recently with the aim of determining the Coulomb breakup components. We reexamine this reaction, and perform one-step quantum-mechanical calculations that include El, E2, and nuclear contributions. We show that the nuclear contribution is by no means negligible at the intermediate angular range where data were taken. Our results indicate that, for an accurate description of this reaction, Coulomb El, E2, and nuclear processes all have to be taken into account.
