Microscopic Analysis of Elastic Scattering of One-Proton Halo Nucleus ¹⁷F on Different Mass Targets

An analysis of cross sections of elastic scattering of F-17 on C-12, N-14, Ni-58, and Pb-208 nuclei at energy 170 MeV and on Pb-208 at various energies is carried out by using the microscopically calculated optical potentials (OPs). The proton and neutron density distributions of the exotic nucleus F-17 are computed in the framework of microscopic models. The real part of the OP with its direct and exchange components that contain isoscalar and isovector contributions is calculated by a corresponding folding procedure accounting for the anti-symmetrization effects. The imaginary part is obtained on the base of the high-energy approximation. In the hybrid model of the optical potential the only free parameters are the depths of the real and imaginary parts of the OPs obtained by fitting the experimental data. A good agreement of the theoretical results with the available experimental data is achieved pointing out clearly to a peripheral character of the scattering.
