To study the energy dependence of incomplete fusion processes, the recoil range distributions for the reactions {sup 181}Ta({sup 16}O,xn), {sup 181}Ta({sup 16}O,pxn), {sup 181}Ta({sup 16}O,alphan), {sup 181}Ta({sup 16}O,alpha2n), {sup 181}Ta({sup 16}O,alpha3n), and {sup 181}Ta({sup 16}O,2alpha3n) have been measured at approx =81-, 90-, and 96 MeV beam energies. The disentanglement of the complete and incomplete fusion processes have been done in terms of full and partial linear momentum transfer from the projectile to the target nucleus. The measurements have been done using recoil catcher technique. The experimentally measured forward recoil range distributions have been interpreted in terms of breakup fusion model. Detailed analysis of the data indicates that incomplete fusion processes have significant contribution at energies as low as approx =5 MeV/nucleon and their contribution is found to increase with energy.
