Transfer vs. Breakup in the interaction of the 7Be Radioactive Ion Beam with a 58Ni target at Coulomb barrier energies

We measured for the first time Be-7 elastically scattered nuclei as well as He-3,He-4 reaction products from a Ni-58 target at 22.3 MeV beam energy. The data were analyzed within the optical model formalism to extract the total reaction cross section. Extensive kinematical, Distorted Wave Born Approximation (DWBA) and Continuum Discretized Coupled Channel (CDCC) calculations were performed to investigate the He-3,He-4 originating mechanisms and the interplay between different reaction channels.
