Abstract: Recently published experimental angular distributions of the reaction 13С(11В, 10В)14С at Еlab(11B) = 45.0 MeV for transitions to the ground states of exit channel nuclei, were analyzed within coupled-reaction-channels method (CRC), applying for 10В + 14С interaction the potentials for systems 10В + 12-20С that were obtained by means of the double-folding method (DF) using modelled shapes for the distributions of nucleons in 10В and 12-20С nuclei. This research aimed to investigate the influence of the surface structure of 12-20С isotopes, reflected accordingly in the constructed potentials for the interaction of 10В + 12-20С, on the results of CRC-calculations and their agreement with experimental data. The difference of CRC cross sections for the direct transfer of a neutron, as the main reaction mechanism, was found to be small when applying DF-potentials calculated for systems 10В + 12-16С in the exit channel of this reaction. Only with DF-potentials for 10В + 17-20С systems used in the exit channel of the reaction 13С(11В, 10В)14С a more notable difference of CRC cross sections against the experimental data and those used for the system 10В + 14С was observed, what originates from more diffuse density distributions of nucleons modelled on the surfaces of isotopes 17-20С in comparison with 14С. As CRC-calculations of transfer reactions are affected by strong couplings between different channels, what can deteriorate the investigation of the influence of slight differences in the shapes of DF-potentials in the interaction region, the measurements of angular distributions for the elastic and inelastic scattering of unstable 15-20С isotopes are desirable, as far as possible, for the investigation of their internal structure and isotopic differences.
