【 摘 要 】

We investigated the reaction induced by the Radioactive Ion Beam7Be on the closed proton shell nucleus58Ni at 22.0 MeV bombarding energy. The7Be beam was produced by means of the in-flight technique with the facility EXOTIC at INFN-LNL (Italy). Charged reaction products were mass and charge identified in a rather wide angular range and their energy distributions were analyzed to infer some information on the production mechanism. The relevance of direct processes, especially3He- and4He-stripping, as well as compound nucleus reactions is critically reviewed.
