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 xn, pxn, and αxn channels were measured in the 16 O + 181 Ta system at energies of ≈76-100 MeV. The experimental excitation functions were compared with those calculated using the theoretical model code PACE4. It was observed that excitation functions of xn/pxn channels are in good agreement with theoretical predictions. However, a significant enhancement in the measured excitation functions of α-emitting channels was observed and attributed to the incomplete fusion processes. The incomplete fusion fraction (F ICF ) that gives the relative importance of complete and incomplete fusion processes was found to increase with energy. The results are discussed in terms of α-cluster structure of the projectile on various fusion reactions.
