摘要：

The validity of cluster-folding (CF) interactions for elastic scattering of Li-6 by various nuclei is investigated in the alpha + d + target three-body model. The Li-6 --> alpha + d breakup process is taken into account in the framework of the continuum-discretized coupled-channels (CDCC). It is shown that, at low energies below E(lab)/A(p) congruent-to 10 MeV, the real part of the CF potentials has to be reduced by about (40-50)%, even when the resonant and non-resonant breakup channels are explicitly included in the CDCC calculations, while no renormalization is necessary for fits to scattering at higher energies.
