Abstract: Angular distributions of the ⁷Li(¹⁰B, ⁹Be)⁸Be were measured at the energy E_lab(¹⁰B) = 51 MeV (21 MeV c.m.) for the ground and excited states of ⁸Bе. The experimental data were analyzed within the coupled-reaction-channels (CRC) method for one- and two-step transfers of nucleons and clusters. The ¹⁰B(⁷Li, ⁹Be)⁸Be reaction data at the energy E_lab(⁷Li) = 24 MeV (14.12 MeV c.m.) known from the literature, were included in the CRC-analysis too. Mechanism of the reactions was determined, the parameters of the ⁸Bе + ⁹Bе-potential were deduced and energy dependence of the parameter was studied.
