摘　　要：The angular distributions of 7Li+144Sm elastic scattering over the energy range of 21.6–52 MeV are reanalyzed utilizing various interaction potentials.The analysis aims to study the consistency of the implemented potentials in representing the considered data and investigate the cluster nature of the weakly bound 7Li projectile.This will aid in the better understanding the impacts of 7Li breakup on the elastic scattering channel.Strong coupling to the breakup channel has a substantial impact on the elastic data and reproduces a repulsive dynamical polarization potential,which drastically diminishes the real potential strength.This reported impact was simulated by introducing a semi-microscopic repulsive DPP and by implementing the method of continuum discretized coupled channels.The analysis was also extended to understand the impact of triton transfer on the elastic scattering data.
