New experimental data for differential cross-sections of the reaction 14C(11B, 10B)15C at Еlab(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 crosssections 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 15С + 10В and 12, 13С + 10В 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. [ABSTRACT FROM AUTHOR] |
