• The excitation functions for three evaporation residues ⁴⁸Cr, ⁸¹Rb, and ⁷⁶Br produced by ¹⁶O-ion beam in interaction with ⁴⁵Sc and ⁷⁴Ge nuclei have been measured in the energy range \approx 66{\mbox{--}}114 MeV, using catcher foil activation technique followed by gamma-ray spectrometry. The measured excitation functions have been compared with a statistical model calculation. The comparison indicates the presence of significant contributions from incomplete fusion in addition to complete fusion reaction. Comparison of above two data sets, suggests that the probability of incomplete fusion increases very slowly with projectile energy for the \text{^{16}O}+ \text{^{45}Sc} system, while the probability of incomplete fusion increases faster with projectile energy for the \text{^{16}O}+ \text{^{74}Ge} system. In addition of that the comparisons of these two data sets also suggest that the complete fusion decreases very slowly with projectile energy for the \text{^{16}O}+ \text{^{45}Sc} system, while in case of \text{^{16}O}+ \text{^{74}Ge} system, complete fusion decreases faster with projectile energy. It indicates that the complete fusion probability decreases with projectile energy and depends on the mass-asymmetry between the interacting partners. Moreover, the incomplete fusion probability is found to increases with increasing entrance channel mass-asymmetry between projectile--target systems.
