NUCLEAR INTERFERENCE EFFECTS IN B-8 SUB-COULOMB BREAKUP

The breakup of B-8 On Ni-58 below the Coulomb barrier was measured rec ently with the aim of determining the Coulomb breakup components. We r eexamine this reaction, and perform one-step quantum-mechanical calcul ations that include El, E2, and nuclear contributions. We show that th e nuclear contribution is by no means negligible at the intermediate a ngular range where data were taken. Our results indicate that, for an accurate description of this reaction, Coulomb El, E2, and nuclear pro cesses all have to be taken into account.
