Abstract: Angular distributions of the ⁷Li(¹⁰B, ¹⁰Bе)⁷Bе reaction were measured at the energy E_lab(¹⁰B) = 51 MeV for the transitions to the ground and excited states of ¹⁰Bе and ⁷Bе nuclei. The measured ⁷Li(¹⁰B, ¹⁰Bе)⁷Bе reaction data as well as only known from the literature ¹⁰B(⁷Li, ⁷Bе)¹⁰Bе reaction data at the energy E_lab(⁷Li) = 39 MeV were analyzed within DWBA method for the direct charge-exchange of the ¹⁰B → ¹⁰Bе, ⁷Li → ⁷Bе nuclei and within the coupled-reaction channels method for one- and two-step transfers of nucleons and clusters such as ¹⁰B → Х → ¹⁰Bе, ⁷Li → Y → ⁷Bе. It was studied the contributions of different mechanisms to the angular distribution of the ⁷Li(¹⁰B, ¹⁰Bе)⁷Bе and ¹⁰B(⁷Li, ⁷Bе)¹⁰Bе reactions. Using data of these reactions, the parameters of the ⁷Bе + ¹⁰Bе potential as well as their energy dependence were deduced by standard fitting procedure. The deduced ⁷Bе + ¹⁰Bе potential is compared with the corresponding folding-potential calculated using nucleon distributions in ⁷Bе and ¹⁰Bе.
