Microscopic description of the quasielastic scattering of exotic light nuclei

The quasielastic scattering of 40-MeV/nucleon B-8 and Be-7 nuclei by C-12, of 29-MeV/nucleon Li-11 nuclei by Si-28, and of 60-MeV/nucleon C-11 and Li-11 isobars by C-12 is analyzed in a microscopic approach. Optical potentials are constructed in the folding model by using the total M3Y effective nucleon-nucleon interaction and nucleon densities calculated by the density-functional method with the same set of parameters for all colliding nuclei. A plausible description of the angular distributions and of the total reaction cross sections for all the above systems was obtained without renormalizing the real part of the potential. Our microscopic analysis sg confirms that Li-11 has a neutron halo and that B-8 and Be-7 have proton skins.
