Abstract

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.
