The Effect of Breakup on Angular Distribution of Scattering Cross Sections in 6He+197Au, 6He+209Bi, and 8He+208Pb Systems at Energies Close to Coulomb Potential Barrier

Abstract

Effects of breakup channel on elastic and inelastic scattering have been studied using the nuclear potential Woods-Saxon (WS) for 6He+197Au, 6He+209Bi, and 8He+208Pb systems, which contain weakly bound nuclei (halo nuclei) as projectiles. The Continuum-discretized coupled-channels CDCC method have been used to employed single channel (SC) and coupled channels (CC) calculations. Cross-sections of elastic and inelastic scattering were extracted from the optical potential fits, to achieve the optimum comparability between the theoretical calculations of dstot/dsR and experimental data 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 in angular distribution.
