摘要

The Li-11 scattering and breakup on protons is considered under the assumption that the Li-11 nucleus consists of two interacting clusters, which are a c = Li-9 core and a h = 2n dineutron halo. The single-particle density of the Li-11 nucleus, amicroscopic optical potential, and the cross section for Li-11+p scattering for various choices of cluster shape are obtained and analyzed by folding the density distribution for either cluster with the probability density for the relative motion of two clusters. A comparison with experimental data of the scattering cross section at low, 60-75 MeV, and intermediate, 700 MeV, energies is performed. The momentum distribution of c fragments upon Li-11 breakup is calculated and studied with a help of the obtained p + c and p + h microscopic optical potentials.
