Abstract

Charged reaction products originated from the interaction of the loosely bound radioactive ion beam 17F (Sp=600 keV) with the proton-shell closed 58Ni target were measured at two colliding energies slightly above the Coulomb barrier. The collected data were analyzed within the framework of the optical model to deduce the reaction cross section and to investigate the role played by inelastic excitations, transfer channels, and the breakup process 17F→16O+p at near-barrier energies. The reaction cross section at the lower 17F energy showed a moderate enhancement (~20%) with respect to that of the system 16O+58Ni. At this energy direct reaction channels were also found to be more relevant than those for the reaction induced from the tightly bound projectile 16O on the same target. Both features could be strongly related to the very low binding energy of the 17F valence proton.
