Mechanisms of ¹³C(¹¹B,⁷Li)¹⁷O reaction at the ¹¹B ion energy 45 MeV

Reaction ¹³C(¹¹B, ⁷ Li) ¹⁷O at the energy E_lab ( 11 B) = 45 MeV for the ground and excited states of the ⁷Li and ¹⁷O nuclei was studied.The reaction experimental data were analyzed within the coupled - reaction - channels method (CRC). The ¹³C + ¹¹B elastic scattering channel and one - and two- step reactions transferring nucleons and clusters were included in the coupling scheme. The spectroscopic amplitudes of nucleons and clusters needed for the CRC - calculations were computed within the translationally invariant shell model (TISM). The Woods - Saxon (WS) potential was used for the entrance reaction channel with the parameters deduced from the CRC - analysis of the ¹¹B + ¹³C elastic scattering experimental data when the potential WS and the folding - potential (DF) with imaginary part, parameters of which were deduced from the fitting of the CRC cross sections to the ¹³C(¹¹B, ⁷Li) ¹⁷O reaction experimental data, were used for the exit ⁷Li + ¹⁷O reaction channel. The parameters of the imaginary WS - potential were deduced in the same way. The parameters of the real part of potential were obtained by fitting it to the peripheral region of the DF - potential. Isotopic differences of the ¹³C(^11B, ⁷Li)¹⁷O reaction cross sections using the parameters of ⁷Li + ¹⁷O, ⁷Li + ¹⁶O and ⁷Li + ¹⁸O interaction for the exit reaction channel were observed
