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 {alpha}xn channels were measured in the {sup 16}O+{sup 181}Ta system at energies of {approx_equal}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 {alpha}-emitting channels was observed and attributed to the incomplete fusion processes. The incomplete fusion fraction (F{sub 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 {alpha}-cluster structure of the projectile on various fusion reactions.
