Abstract

The dynamics of heavy-ion fusion reaction involved in the interaction of 12C,14N and 16O projectiles  with,59Co, 51V,128Te  and165Ho  targets  at≈3-8MeV/nucleon  specific  energies was  studied.  This  study  focus  on  the  correlation  between  entrance  channel  properties  and  incomplete  fusion  reaction.  The  experimentally  measured  excitation  functions  of  various  reaction  products  populated  by  complete  and/or  incomplete  fusions  of  12C+59Co, 128Te,14N+128Teand 16O+ 51V, 165Hoprojectile-target systems available in the literature. Were compared and analyzed with the predicted excitation functions, using the statistical model code PACE4. For representative non-α-emittingchannels,  the  experimentally  measured  excitation functions were, in general, found to be in good agreement with the theoretical predictions.  However,  for  α-emitting  channels  in  the  present  systems,  the  measured excitation functions were higher than the predictions of the theoretical model code, which may  be  credited  to  incomplete  fusion  reactions  at  these  energies.  An  attempt  was  made  to  approximate  the  incomplete  fusion  fraction  that  explains  the  relative  importance  of  incomplete fusion processes. The incomplete fusion fraction was found to be sensitive to the projectile energy and mass-asymmetry of the entrance channel.
