Kyryanchuk V. Kyryanchuk V.M. Scattering and transfer reactions in collisions of 9Be + 11B nuclei.

The thesis includes the results of studies of nuclear processes caused by the 9Be + 11B collisions. New experimental data of the elastic and inelastic scattering of 9Be + 11B as well as the 9Be(11B,10B)10Be, 9Be(11B,12B)8Be, 9Be(11B,11C)8Li reactions were obtained at the energy Elab(11B) = 45 МеV. Angular distributions of the 9Be + 11B elastic and inelastic scattering were analyzed within the optical model (OM) and coupled-reaction-channels (CRC) method. Data of the 11B + 9Be elastic scattering at Ecm 9 - 22 MeV known from the literature also included in analysis. The mechanisms of the 9Be + 11B anamalous large angle scattering were studied both for the elastic and inelastic channels including the 9Be and 11B reorientations and transfer reactions. The optical potential parameters for 9Be + 11B elastic scattering and the 9Be and 11B deformation parameters were deduced. Angular distributions of the 9Be(11B,10B)10Be, 9Be(11B,12B)8Be, 9Be(11B,11C)8Li reactions for the transitions to the ground and excited states of the outgoing nuclei were analysed within the CRC method. One- and two-step transfers of nucleons and clusters were included in the coupling scheme. The optical potential parameters were deduced for 10B + 10Be, 12B + 8Be, 11C + 8Li interactions. Elastic scattering of 9Be + 10B at energies Ecm 8,42 - 47,37 MeV known from the literature were also analyzed in order to study isotopic effect for the 9Be + 10B, 9Be + 11B, 10B + 10Be channels. The energy dependence of the 9Be + 10B and 10Be + 10B OM potential parameters were deduced. Isobaric and isotopic effects were investigated in the angular distributions of the 9Be(11B,12B)8Be and 9Be(11B,11C)8Li, 9Be(11B,12B)8Be and 9Be(11B,10B)10Be.
