Abstract.

Fusion cross-sections for the 7Li  + 12C reaction have been measured at energies above the Coulomb barrier by the direct detection of evaporation residues. The heavy evaporation residues with energies below 3 MeV could not be separated out from the a-particles in the spectrum and hence their contribution was estimated using statistical model calculations. The present work indicates that suppression of fusion cross-sections due to the breakup of  7Li    may not be significant for 7Li  + 12C reaction at energies around the barrier.

Keywords:  Fusion; breakup; light ion fusion.
