Microscopic Description of 8Li+Nucleus and of 8B+Nucleus Scattering

We apply a microscopic version of the Continuum Discretized Coupled Channel (CDCC) method, referred to as MCDCC, to 8Li and 8B scattering on different targets. The 8Li and 8B nuclei are described in a microscopic three-cluster model (a + t + n and a + 3He + p), using the hyperspherical coordinates. We first present spectroscopic properties of these nuclei. Then, we determine 8Li+ nucleus and 8B+ nucleus potentials by using proton+ target and neutron+ target interactions. We compute various elastic-scattering cross sections and confirm that breakup effects are important, in particular at lowenergies. In general, we find a fair agreement with experiment, except for 8B + 58Ni where we suggest that the data might be overestimated.
