Linear momentum transfer in incomplete fusion reactions of C-12 and C-13 with Ta-181

摘要

Recoil range distribution of evaporation residues formed in complete and incomplete fusion of 82.5 MeV C-12 and C-13 with Ta-181 have been measured by recoil catcher technique followed by off-line gamma-ray spectrometry. The recoil range distributions of incomplete fusion products were found to be in good agreement with that simulated on the basis of direct surface transfer reaction model. The cross-sections for complete and incomplete fusion were delineated from the measured excitation function data at the same beam energy. The fraction of incomplete fusion in the total cross-section was found to be more in the case of C-12 than that in the case of C-13 indicating the dependence of incomplete fusion probability on the cluster structure of the projectile.
