Abstract: Continuous efforts are being made to comprehend the process of low energy incomplete fusion (ICF) reaction dynamics. The lack of proper theoretical model below 8 MeV/nucleon, which could reproduce the experimentally measured ICF data satisfactorily, makes it the topic of great interest. Another important motivation is to look for some systematic dependence of ICF on various entrance channel parameters. Keeping the aforementioned aspects into consideration, the experiment has been performed using 12C ion beam on 165Ho target by employing the stacked foil activation technique. The experimentally measured cross sections of the populated evaporation residues have been measured and compared with the complete fusion code PACE4. It has been observed that the measured cross sections for evaporation residues populated via xn and pxn emission channels are well reproduced by PACE4 code. However, in the α-emission channels (observed in the projectile break-up), the significant enhancement in the measured cross sections over PACE4 predictions is observed which is accredited to ICF process. In the present work, ICF dependence on the target deformation and the combined parameter µ * ZPZT * (1-β2) has been studied. The ICF fraction has also been found sensitive to projectile Qα- value.
