| Summary: | The reaction 13C(11B,12C)12B at Еlab(11B) = 45 MeV was investigated for the ground states of 12C and 12B nuclei and excited states of 12B nucleus. New experimental data for the angular distributions of the reaction cross-sections were obtained. The experimental data were analyzed within the coupled-reaction-channels method (CRC). The 13C + 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 parameters deduced previously from the analysis of the experimental data of 11B + 13C elastic and inelastic scattering, whereas the WS potential for the exit 12C + 12B reaction channel was deduced from the fitting of CRC cross-sections to the 13C(11B,12C)12B 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 direct mechanisms of the transfers of nucleons and clusters were investigated in this reaction. The 12С + 12В potential parameters were deduced and comparisons of the CRC reaction cross-sections calculated with the 12C + 12B and 12C + 10,11B potential parameters were performed. The differences between these CRC calculations were observed. The "isotopic effects" were observed for the potentials of 12C interactions with boron isotopes 10, 11, 12B. |
