Abstract: Angular distribution of the ⁹Ве(¹¹В, ¹²В)⁸Ве reaction were measured at Е_lab(¹¹В) = 45 MeV for the transitions to the ground states of ¹²В and ⁸Ве and to the 0.953 МеV (2⁺) excited state of ¹²В and 2.94 MeV (2⁺) excited state of ⁸Be. The data were analyzed within the coupled-reaction-channels (CRC) method. One- and two-step transfers of nucleons and clusters were included in the coupling scheme. It was found that the neutron transfer dominates in the ⁹Ве(¹¹В, ¹²В)⁸Ве reaction. The parameters of the ¹²В + ⁸Ве optical model potential were deduced.
