New experimental data for differential cross-sections of the 14C( 11B, 12C) 13B reaction obtained recently at the energy Еlab( 11B) = 45 MeV for the ground states of 13B and 12C were analyzed within the coupled reaction channels (CRC) method that included the 11B + 14C elastic scattering channel as well as channels for one- and two-step transfers of nucleons in the coupling scheme. The necessary 11B + 14C Woods - Saxon (WS) optical potential parameters for the entrance reaction channel were obtained from 11B elastic scattering in the previous work, while those for 12C + 13B interaction were deduced from fitting the CRC calculations to the 14C( 11B, 12C) 13B reaction data. Needed spectroscopic amplitudes of transferred nucleons and clusters were calculated within the translational-invariant shell model. The data are well described by the direct transfer of a proton while contributions from two-step transfers were found to be negligible. The deduced 13B + 12C WS optical potential parameters are compared with those of the 10,11,12B + 12C nuclei interactions. The effect of isotopic differences in these interactions was observed.

Angular distributions of the 7Li + 12C elastic and inelastic scattering as well as the 7Li(14N, X) reactions with exited stable and unstable nuclei with Z = 3-6 were measured at Elab(12C) = 115 MeV. The data were analyzed within the optical model and coupled-reaction-channels method. The elastic and inelastic scattering, reorientations of 7Li in ground and excited states as well as more important transfer reactions were included in the channels-coupling-scheme. 7Li + + 12C optical potential parameters for ground and excited states of 7Li and 12C as well as deformation parameters of these nuclei were deduced. The contributions of one- and two-step transfers in the 7Li + 12C elastic and inelastic scattering channels were estimated. [ABSTRACT FROM AUTHOR]

New experimental data for differential cross sections of the 14C(11B, 9Be)16N reaction were measured for the ground states of 9Be and 16N nuclei as well as for the excited states of 16N at the energy Elab.(11B) = 45 MeV. The reaction data were analyzed within the coupled-reaction channels method (CRC) for one- and two-step transfers of nucleons and clusters. In the CRC-calculations, the optical potential deduced from the analysis of the 11B + 14C elastic scattering data was used for the entrance reaction channel. Needed spectroscopic amplitudes of nucleons and clusters in nuclei were calculated within shell-model. 9Be + 16N optical potential parameters were deduced by fitting CRC cross-sections to the 14C(11B, 9Be)16N reaction data. Contributions of one- and two-step transfers of nucleons and clusters into the 14C(11B, 9Be)16N reaction cross-sections were obtained. [ABSTRACT FROM AUTHOR]

Angular distributions of the 6Li(18O, 17O)7Li reaction were measured at Elab(18O) = 114 MeV for ground and excited states of exit nuclei. The data were analyzed within the coupled-reaction-channels method (CRC). The 6Li + 18O elastic and inelastic scattering channels as well as the simplest one- and two-step reactions were included in the coupledreaction- channels scheme. In CRC calculations, the 6Li + 18O potential with parameters deduced from the elastic scattering data, was used for the entrance reaction channel.

New experimental data for differential cross sections of 14C(11B, 11B)14C inelastic scattering at the energy Elab.(11B) = 45 MeV for transitions of 11B nucleus to the excited states of 2,12 - 8,56 MeV were obtained. Experimental 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 14C + 11B interaction and deformation parameters of 11B nucleus were deduced. Optical potential, deduced from the fit of experimental data, is compared to the respective foldingpotential, calculated by the method of double-folding. Isotopic differences of optical model potentials for 12,13,14C + 11B interaction, using the results of recent publications of 12,13C + 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 14C + 11B scattering were defined. [ABSTRACT FROM AUTHOR]
