Abstract
An attempt has been made to investigate for the reaction dynamics leading to incomplete fusion (ICF) of heavy ions at moderate excitation energies, especially the influence of incomplete fusion on complete fusion (CF) of O-16 induced reactions at specific energies. Excitation functions (EFs) of various reaction products populated via CF and/or ICF of O-16 projectile with Sc-45 target were measured at energies approximate to 3-7 MeV/nucleon, using recoil catcher technique followed by offline gamma-ray spectroscopy. The measured EFs were compared with theoretical values obtained using the statistical model code PACE4. The experimentally measured EFs were in general found to be in good agreement with the theoretical predictions for non alpha- emitting channels in the present target projectile system. However, for alpha-emitting channels the measured EFs were higher than the predictions of the theoretical model codes, which may be credited to incomplete fusion reactions at these energies.
