Mechanisms of ¹⁴C(¹¹B, ¹⁰B)¹⁵C reaction at energy 45 MeV for ground and excited states of ¹⁰B and ¹⁵C nuclei

New experimental data for differential cross-sections of the reaction ¹⁴C(¹¹B, ¹⁰B)¹⁵C at E_lab(¹¹B) = 45 MeV were obtained for transitions to the ground and excited states of the exit reaction channel nuclei. The experimental data were analyzed within the coupled-reaction-channels method (CRC). The ¹⁴C + ¹¹B elastic scattering channel as well as channels for one- and two-step transfers of nucleons and clusters were included in the coupling scheme. The Woods - Saxon (WS) potential was used in the CRC-calculations for the entrance reaction channel with the parameters deduced previously from the analysis of the experimental data of ¹¹B + ¹⁴C elastic and inelastic scattering, whereas the WS potential for the exit ¹⁵C + ¹⁰B reaction channel was deduced from the fit of CRC cross sections to the ¹⁴C(¹¹B, ¹⁰B)¹⁵C reaction experimental data. Needed for CRC-calculations spectroscopic amplitudes (factors) of the nucleons and clusters transferred in the reaction were calculated within the translational-invariant shell model. The mechanisms for one- and two-step transfers of nucleons and clusters were investigated in this reaction. The ¹⁵C + ¹⁰B potential parameters were deduced, and comparisons of the CRC reaction cross-sections calculated with the ¹⁵C + ¹⁰B and ^{12, 13}C + ¹⁰B potential parameters were performed. The differences between these CRC calculations were observed, e.g. "isotopic effects" were observed for the potentials of ¹⁰B interaction with ^12,13,15C carbon isotopes. (author)
