Analysis - experiments with heavy ions, measurements of angular distributions of differential cross sections by use of semiconductor, ionization and scintillation detectors; theoretic analysis in frame of Couple Reactions Channels (CRC) - technique. The goal of investigation - estimation of direct multi-step transfers of nucleons and clusters in the interactions, induced by heavy-ions on light nuclei at the energy ? 20 АМeV; investigation of fundamental regularity in light nuclear structures and measure of micro- and macroscopic properties of p-shell nuclei. The new experimental data of elastic and inelastic scattering and few nucleon transfer reactions, induced by 11В on 7Li, 9Be and 12,14C for the transitions at the ground and some excited states are presented. Results of theoretical interpretation of experimental data within the optical model (OM) and CRC- method are summarized. It was shown that one- and two-step reaction mechanisms depending on nuclear structure can contribute significantly on experimental cross sections. The threshold anomalies in 9Ве + 12С, 8Ве + 13С и 10В + 11В interactions as well as isotopic and isobaric effects in the reaction angular distributions and nucleus-nucleus interactions were studied. The energy dependence of nucleus-nucleus potentials OM for the stable and unstable ejectiles at Еc:m"7-21 MeV was deduced. Product Description popup.authors popup.nrat_date 2020-04-02 Close
