Abstract
Measurement of forward recoil range distribution (FRRD) of evaporation residues (ERs) populated in the reaction at MeV have been carried out by employing the offline characteristic -ray detection method. The FRRD pattern of ERs populated through / channels comprises a single peak only whereas ERs populated through emitting channel have multiple peaks in their FRRD. FRRDs of the observed ERs support the presence of the complete fusion (CF) process in the population of / channels residues and an admixture of complete and incomplete fusion (ICF) processes in the population of emitting channel residues. The observed ICF process in the population of emitting channel residues is explained through the breakup fusion model. The fusion function is derived from the experimental CF cross section data and the extracted fusion function is compared with the universal fusion function to estimate the degree of ICF contribution to the total fusion cross section. An attempt has also been made to explore the dependence of ICF probability on target charge.
