Abstract
An experiment was carried out to explore heavy ion incomplete fusion reaction dynamics, within the framework of the break-up fusion model, at energies near and above the Coulomb barrier. Excitation functions for several radionuclides produced via , , and channels were measured in the system at energies of MeV. The experimental excitation functions were compared with those calculated using the theoretical model code PACE4. It was observed that excitation functions of channels are in good agreement with theoretical predictions. However, a significant enhancement in the measured excitation functions of -emitting channels was observed and attributed to the incomplete fusion processes. The incomplete fusion fraction () that gives the relative importance of complete and incomplete fusion processes was found to increase with energy. The results are discussed in terms of -cluster structure of the projectile on various fusion reactions.
