Investigation of the Projectile Breakup Effects on Elastic Scattering and Fusion for 9Be + 209Bi System at Around Barrier Energies
Abstract
The influence on elastic scattering angular distribution (ESAD) and total fusion (TF) excitation function of couplings to breakup channel has been investigated for 9Be + 209Bi system at near and above barrier energies. The three body continuum discretized coupled channel (CDCC) calculations, (two body (8Be + n) projectile and target), are performed by making use of the code FRESCO. The ESADs are found to be in good accord with experimental observations. However, an enhancement is observed in the CDCC predictions of total fusion excitation function with respect to the data when breakup couplings are taken into account.
