Abstract

Experiments with secondary radioactive beams \(^6\)He, \(^7\)Be, \(^8\)Li and \(^8\)B on several targets have been performed in recent years at the Radioactive Ion Beams facility in Brasil (RIBRAS). We present results of elastic scattering and reaction measurements performed with this facility. A preliminary Coulomb excitation experiment using gamma-particle coincidence technique is described.
