Description |
A representation of the fusion barrier distributions has been deduced from the back angle quasielastic scattering cross section data in O-1618+ Sn-12,Sn-124 reactions, measured over a wide range of bombarding energies around the Coulomb barrier. The results have been compared with coupled channel calculations using the CCDEF code to study the effects of projectile and target inelastic excitations and nucleon transfer couplings on the representation of fusion barrier distributions in these systems. The present studies bring out the importance of coupling of 2n pickup in the O-16+ Sn-120,Sn-124 reactions and 2n stripping in the O-18+ Sn-120,Sn-124 reactions in explaining the observed barrier distributions.
