Microscopic analysis of $^{11}$Li elastic scattering on protons and breakup processes within $^{9}$Li+$2n$ cluster model
Abstract
In the paper, the results of analysis of elastic scattering and breakup processes in interactions of the Li nucleus with protons are presented. The hybrid model of the microscopic optical potential (OP) is applied. This OP includes the single-folding real part, while its imaginary part is derived within the high-energy approximation (HEA) theory. For the Li elastic scattering, the microscopic large-scale shell model (LSSM) density of Li is used. The depths of the real and imaginary parts of OP are fitted to the elastic scattering data at 62, 68.4, and 75 MeV/nucleon, being simultaneously adjusted to reproduce the true energy dependence of the corresponding volume integrals. The role of the spin-orbit potential is studied and predictions for the total reaction cross sections are made. Also, the cluster model, in which Li consists of -halo and the Li core having its own LSSM form of density, is adopted. The respective microscopic proton-cluster OP's are calculated and folded with the density probability of the relative motion of both clusters to get the whole Li optical potential. The breakup cross sections of Li at 62 MeV/nucleon and momentum distributions of the cluster fragments are calculated. An analysis of the single-particle density of Li within the same cluster model accounting for the possible geometric forms of the halo-cluster density distribution is performed.
