Abstract

• In this work, we have studied the fusion cross sections and fusion barrier distributions of heavy-ion collision at energy near and below the Coulomb barrier. The coupled-channels method has been applied to analyze the intrinsic characters of colliding systems. Firstly, we evaluate fusion cross sections for systems having different collective environments. Next, we calculate the fusion cross section and fusion barrier distribution for fixed projectile and different target (i.e., 16O + AX systems where the target has different intrinsic characters such as rotation and vibration). To this end, we compare the experimental fusion cross sections with those from calculations with and without coupling using the same potential parameters of the selected systems. The calculated results indicate the sensitivity of fusion cross sections on types of static and dynamic deformations. The results show that the coupled-channels calculations reproduce the fusion cross sections very well but barrier distribution deviate from the experimental results in the high energy region.
