Elastic alpha-transfer in the elastic scattering of 16-O+12-C

The elastic-scattering 16O + 12C angular distributions at 16 O bombarding energies of 100.0, 115.9 and 124.0 MeV and their optical-model description including the <alpha>-particle exchange contribution calculated in the Coupled Reaction Channel (CRC) approach are presented. The angular distributions show not only the usual diffraction pattern but also, at larger angles, intermediate structure of refractive origin on which finer oscillations are superimposed. The large-angle features can be consistently described including explicitly the elastic <alpha>-transfer process and using a refractive optical potential with a deep real part and a weakly absorptive imaginary part.
