Elastic and inelastic scattering of 11B ions by 14C at 45 MeV

Abstract

New experimental data for differential cross sections of 14С(11B, 11B)14С inelastic scattering at the energy Elab.(11В) = 45 MeV for transitions of 11B nucleus to the excited states of 2,12 - 8,56 MeV were obtained. Experi-mental data were analyzed within optical model and coupled-reaction channels method. Elastic and inelastic scattering of nuclei, reorientation of spin of 11B and simplest transfers of nucleons and clusters were included in the coupling scheme. Woods - Saxon optical model parameters of 14С + 11B interaction and deformation parameters of 11B nu-cleus were deduced. Optical potential, deduced from the fit of experimental data, is compared to the respective folding-potential, calculated by the method of double-folding. Isotopic differences of optical model potentials for 12,13,14С + 11B interaction, using the results of recent publications of 12,13С + 11B elastic and inelastic scattering at similar energies, were investigated. Contributions of one- and two-step transfers of nucleons and clusters into the elastic and inelastic channels of 14С + 11B scattering were defined.
