Role of partial linear momentum transfer on incomplete fusion reaction

. Measurements of forward recoil range distributions (FRRDs) of the evaporation residues, populated in the 20 Ne+ 51 V reaction at E l a b ≈ 145 MeV, have been carried out using the offline characteristic γ -ray detection method. The observation does corroborate the presence of complete fusion (CF) process in the population of p xn channel residues and both complete as well as incomplete fusion (ICF) processes in the population of α emitting channel residues. The FRRDs of p xn channel residues comprise single peak only, whereas α emitting channel residues have multiple peaks in their FRRDs. CF cross section data were used to extract the fusion functions. Extracted fusion functions were found to be suppressed with respect to the universal fusion function which is used as a uniform standard reference. The observed contribution arising from the ICF process in the population of α emitting channel residues is explained in terms of breakup fusion model.
