Study of 16O+12C and 16O+14C elastic scattering

The observation of nuclear rainbow phenomenon in some light nuclei collisions provides unique possibility to study nucleus-nucleus interactions at small distances. The valuable information on nuclear potentials of light heavy ions was obtained by investigation of 16O+16O and 12C+12C elastic scattering. However, due to the fact that these systems are symmetric the meaningful angular distributions are limited by 90 deg. The neighbor asymmetrical combination 16O+12C seems more suitable from this point of view for studies in the energy region 10-20 MeVxA. We undertook systematic study of elastic scattering in this system at several 16O energies between 130 and 260 MeV. Well-developed rainbow patterns including the supernumerary Airy structures were observed. The potential parameters both from phenomenological (WS1) or folding calculations connected smoothly the results at higher and lower energies
