The difference of the surface structure of carbon isotopes, its impact on the calculations of the 13C(11B, 10B)14C reaction cross sections

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.
