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.

雅克·雷纳尔（Jacques Raynal）的ECIS（EquationsCoupléesItérationsSéquentielles）编码自上个世纪七十年代以来一直发挥着重要作用。用它来描述轻质重离子在接近库仑势垒的能量下的弹性和非弹性散射是本文的首要主题。在第二个主题中描述了具有弱约束的稳定弹丸和放射性弹丸的核反应，在ECIS中未考虑弹丸的破裂，并且对它们应用了一种最新的形式主义，即连续离散耦合通道（CDCC）计算。第二个主题还包含在巴西的放射性离子束（RIBRAS）设施上获得的一些结果，其中放射性2n-卤代\（^ 6 \） He束对轻，中质量和重目标进行了照射。
