✦ Synopsis

Angular distributions of the 9 Be( 12 C, 11 B) 10 B reaction were measured at the energy of E lab ( 12 C) = 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 10 B nucleus and 2.12 MeV (1/2 -) + 2.15 MeV (1 + ) excited states of 11 B and 10 B 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 + p)-, ( 3 He + p)-and ( 3 He + d)-transfer mechanisms were included in the coupled channel scheme. It was found that two-step processes are important for all transitions. Data of 10 B + 10 B elastic scattering from the literature were included in the analysis of the energy dependence of optical model parameters for 10 B + 10 B and 10 B + 11 B interactions. A good description of all sets of experimental data was achieved.
