Aiming to investigate the presence of incomplete fusion at low projectile energies, experiments have been carried out using light heavy-ion (A ≤ 16) beams at ≈ 4-7 MeV/nucleon. Excitation functions, forward recoil ranges, and spin-distributions of heavy reaction products have been measured. In order to have an insight into the influence of incomplete fusion on complete fusion, percentage fraction of incomplete fusion has been deduced from the experimentally measured excitation functions. However, the proof of fractional linearmomentum transfer in case of incomplete fusion has been obtained from the measurement of forward recoil ranges of heavy reaction products. A piece of information on driving angular momenta involved in the production of xn/pxn/αxn/2αxn-channels has been obtained from the analysis of experimentally measured spin-distributions. Results presented in this paper strongly suggest that incomplete fusion is a process of greater importance at energies ≈ 4-7 MeV/nucleon and can selectively populate high spin states in final reaction products.
