Fusion reactions including weakly-bound and halo nuclei around Coulomb barrier

In this study, we investigate fusion cross sections including halo and weakly-bound nuclei around Coulomb barrier. We reviewed our previous results for the total fusion cross sections of the He-6+ Bi-209, Li-11+ Pb-208 and C-14,C-15+ Th-232 systems, which involve well-known halo nuclei. Then, to analyze the total fusion reaction of neutron-rich nuclei, Li-9 + Zn-70 system, we introduced the coupled channel method for a two-neutron transfer in the fusion reaction practically. To study the neutron rich projectile nucleus of this system (Li-9), we constructed a folding potential with projectile and target densities using charge density distribution. Finally, we analyzed the fusion cross section of the Li-9 + Zn-70 system in one or two channel coupled manners. By adjusting the coupling strength and effective Q-value of the coupling form factor, we successfully reproduced the experimental fusion cross-section data for this system. Our results indicate that the two-neutron transfer channel plays a critical role in the fusion reactions of neutron-rich nuclei, such as Li-9 nuclei at energies around the Coulomb barrier.
