【 摘 要 】

Excitation functions of reaction products formed in 16O+66Zn and 37Cl + 45Sc systems, leading to the same compound nucleus, 82Sr, were measured using recoilcatcher technique and off-line 𝛾-ray spectrometry. The contribution of non-compound processes like transfer and incomplete fusion (ICF) reactions to the cross-sections of different evaporation residues were delineated by comparing the experimental data with the predictions of Monte Carlo simulation code PACE2. The results show that non-compound processes become a significant fraction of the total reaction cross-section in 16O+66Zn systems in the beam energy range studied, while 37Cl + 45Sc gives mainly compound nucleus products. The mass asymmetry dependence of the fusion and non-compound cross-sections have been analysed in terms of the static fusion model and sum rule model.
