Effect of Coupling Channel on Elastic Scattering for 6He+208Pb, 7Be+58Ni and 7Li+59Co Systems

Effects of coupling channel on elastic scattering have been studied using the nuclear potential Woods-Saxon (WS) for 6He+208Pb, 7Be+58Ni and 7Li+59Co systems. The Continuum-discretized coupled-channels CDCC method have been used to employed no coupled and coupled-channels (CC) calculations for unstable projectiles. Cross-sections of elastic scattering were extracted from the optical potential fits, to achieve the optimum comparability between the theoretical estimates of dσel/dσR and empirical values for the systems reviewed. The breakup process at near Coulomb barrier energies play essential role in the results of cross section as a function of angle and energy in addition to the distribution of the barrier.
