Influence of incomplete fusion reaction on complete fusion below 10 MeV/ nucleon energies

An attempt has been made in the present work to provide an ample opportunity to explore the information about the influence of incomplete fusion (ICF) reaction dynamics on complete fusion in heavy ion induced nuclear reactions. Excitation functions for several evaporation residues produced in the interaction of projectile ¹⁶O with target ¹⁷⁵Lu have been measured over the wide projectile energy range ≈ 70-100 MeV. The recoil-catcher activation technique followed by the offline γ-ray spectroscopy has been used for the present measurements. In case of precursor decay, we have made use of Cavinato et al. formulation to calculate the independent cross-section of the identified residues. The measured EFEFs are compared with theoretical predictions of statistical model code PACE-2 and any enhancement in the measured cross-section from theoretical prediction may be due to ICF reaction process. An attempt has been made to estimate the ICF contribution of the cross-section from the measured excitation function data and the dependence of ICF cross-section on projectile energy. (author)
