The ECIS (Equations Couplées Itérations Séquentielles) code of Jacques Raynal continues to have an important role since its first version in the seventies. Its use to describe the elastic and inelastic scattering of light heavy ions at energies close to the Coulomb barrier is the first topic of this paper. Nuclear reactions with weakly bound stable and radioactive projectiles are described in the second topic, where the projectiles breakup is not taken into account in ECIS and a more recent formalism called Continuum Discretized Coupled Channels (CDCC) calculations is applied to them. The second topic also contains some results that were obtained at the Radioactive Ion Beams in Brasil (RIBRAS) facility, with a radioactive 2n-halo 6 He beam on light, medium mass, and heavy targets.

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.

The availability of radioactive beams provides new opportunities in nuclear physics [1]. On the one hand, they provide a probe of the nuclear structure in unusual conditions of excitation energy and isospin. Many experiments have been performed with beams such as6He,8He11Li,11Be, among others (see references in Ref. [1]). At energies near the Coulomb barrier or above, these experiments provide valuable information on the structure of exotic nuclei and on the dynamics of the nuclear reactions between them. On the other hand, recent experiments involving radioactive beams have been very successful in nuclear astrophysics, where many stellar scenarios involve short-lived nuclei [2].

Abstract: The RIBRAS facility (Radioactive Ion Beams in Brasil) is installed in connection with the 8MV Pelletron tandem of the University of São Paulo Physics Institute. It consists of two superconducting solenoids which focalize light radioactive secondary beams of low energy, produced by transfer reactions. Recent experimental results include the elastic scattering and transfer reactions of 6He halo nucleus on 9Be, 27Al, 51V and 120Sn targets. The elastic scattering and transfer of 8Li and 7Be on several targets is also being studied. The transfer reaction 8Li(p,α)5He of astrophysical interest was also studied in the energy range.
