Abstract
The complete and incomplete fusion along with one neutron stripping and pickup cross sections for the system are measured using online and offline characteristic -ray detection techniques. The complete fusion (CF) cross sections at energies above the Coulomb barrier are found to be suppressed by compared to the coupled channel calculations. This suppression observed in complete fusion cross sections is found to be commensurate with the measured total incomplete fusion (ICF) cross sections. There is a distinct feature observed in the ICF cross sections, i.e., capture is found to be dominant than capture at all the measured energies, contrary to the data available for systems. The total fusion cross section ratio between and induced reactions shows an increasing trend as the energy decreases below the barrier while it remains unity at above-barrier energies. A simultaneous explanation of complete, incomplete, and total fusion (TF) data is also obtained from the calculations based on the continuum discretized coupled channel method with short-range imaginary potentials. The cross section ratios of CF/TF and ICF/TF obtained from the data as well as the calculations shows the dominance of ICF at below-barrier energies and CF at above-barrier energies.
