英文摘要	The effects of breakup reactions on elastic and cc-production channels for the Li-6+Sn-116 system have been investigated at energies below and near the Coulomb barrier. The angular distributions of alpha-particle production differential cross sections have been obtained at several projectile energies between 22 and 40 MeV. The measured breakup alpha-particle differential cross sections and elastic scattering angular distributions have been compared with the predictions of continuum-discretized coupled channels (CDCC) calculations. The influence of breakup coupling has also been investigated by extracting dynamic polarization potentials (DPP) from the CDCC calculations. From the predictions of CDCC calculations the relative importance of the nuclear, Coulomb, and total breakup contributions have also been investigated. The nuclear breakup couplings are observed to play an important role in comparison to the Coulomb breakup for the direct breakup mechanisms associated in the reaction of Li-6 projectile with Sn-116 target nuclei. The influence of strong nuclear breakup coupling exhibits suppression in the Coulomb-nuclear interference peak. The direct breakup cross sections from the CDCC calculations under-predict the measured alpha-particle differential cross sections at all energies. This suggests that the measured alpha particles may also have contributions from other possible breakup reaction channels.
