Competition between direct and dissipative processes in the binary channels of the 16O + 12C and 18O + 12C reactions

The two reactions, 16O + 12C and 18O + 12C were studied in the energy range between 5 and 10 MeV per nucleon. The binary fragments were identified at the large scattering angles using the kinematic coincidence method. The energy distributions of the dominant binary channels, and the angular distributions of the strongest populated states are presented. The differences between the two entrance channels are discussed. The evolution of the reaction mechanism from quasi-elastic to fully damped processes are presented as a function of bombarding energy, scattering angle, excitation energy and number of transferred nucleons.
