Abstract

Elastic scattering angular distributions have been measured for Li+Mo systems in the bombarding energy range of 0.85 to almost two times the Coulomb barrier. The measured elastic scattering angular distributions are fitted using optical model to investigate energy dependence of the real and imaginary strength parameters with phenomenological Woods-Saxon and double folding So Paulo potentials. Both interaction potential models simulate similar patterns to energy dependence sustaining the same consequence of breakup threshold anomaly. The results of Continuum Discretized Coupled Channels (CDCC) Calculations with inclusion of the breakup coupling of the projectile compares experimental elastic scattering angular distribution better for the Li+Mo systems rather than excluding breakup coupling. A systematic behaviour of total reaction cross section on target and projectile dependency has been investigated by including a wide range of target mass and tightly to weakly bound projectiles. A comparative study on obtained breakup and reaction cross sections has also been carried out for Li+Mo systems.
