摘要

The complete and incomplete fusion along with one neutron stripping and pickup cross sections for the Li-6 + Sn-124 system are measured using online and offline characteristic gamma-ray detection techniques. The complete fusion (CF) cross sections at energies above the Coulomb barrier are found to be suppressed by similar to 34% 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., d capture is found to be dominant than a capture at all the measured energies, contrary to the data available for Li-6 + Bi-209, Au-197 systems. The total fusion cross section ratio between Li-6 and Li-7 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-bamer energies and CF at above-barrier energies.
