In this paper, we have made an attempt to measure the excitation functions for the evaporation residues identified in the interaction of 16O+55Mn system with a view to study the complete and incomplete fusion reaction dynamics in heavy ion induced reactions. The motivation of this experiment is to study the breakup of 16O in reactions below 7 MeV/A and to compare the excitation functions for 12C, 16O and 20Ne induced reactions with different targets leading to the same composite system (71As in this case). PACE-4 and ALICE-91 have been used for the analysis with the same set of input parameters as those adopted in the case of 12C+59Co and 20Ne+51V systems. The measured excitation functions for a particular decay channel in the three cases (i.e. 12C+59Co, 16O+55Mn and 20Ne+51V) have been compared and found to obey Bohr′s assumption in case of complete fusion channels. The effects of Coulomb barrier and other entrance channel parameters are found to be quite significant in determining the decay mode of the composite system. Further the incomplete fusion dynamics is also observed to be of considerable importance in the present energy region.
