One- and two-step mechanisms of the 9Be(12C,11B)10B reaction at Elab(12C)=65 MeV and the energy dependence of 11,10B+10B interactions

Angular distributions of the Be-9(C-12, B-11)(10)g reaction were measured at the energy of E-lab(C-12) = 65 MeV for transitions to the ground and 0.72 MeV (1(+)), 1.74 MeV (0(+), T = 1), 3.59 MeV (2(+)) excited states of the B-10 nucleus and 2.12 MeV (1/2(-)) + 2.15 MeV (1(+)) excited stares of 11B and 10B nuclei, respectively. Data were analyzed within the coupled reaction channel (CRC) model including one- and two-step transfer mechanisms. The elastic and inelastic scattering and p-, d-, (d + n)-, (n f +)-, (He-3 + p)- and (He-3 + d)-transfer mechanisms were included in the coupled channel scheme. It was found that two-step processes are important for all transitions. Data of B-10 + B-10 elastic scattering from the literature were included in the analysis of the energy dependence of optical model parameters for B-10 + B-10 and B-10 + B-11 interactions. A good description of all sets of experimental data was achieved. (C) 2000 Elsevier Science B.V. All rights reserved.
