Abstract

Angular distributions of the elastic and inelastic scattering of 13C ions on 12C nuclei were measured on the heavy-ion Warsaw Cyclotron at the energy of 32.5 MeV in the laboratory system. Elastic scattering in the forward hemisphere is well described by the standard optical model, while at the same time the possible rise of the cross section in the backward direction can be only reproduced with taking into account the contribution of the neutron transfer mechanism. The experimental data on elastic and inelastic scattering have been analyzed within the framework of the optical model and the Coupled Reaction Channels method via code FRESCO.
