Coupled channel and optical model approaches to low-energy heavy-ion reactions

초록

We describe theoretical backgrounds for the coupled channel and the optical model approaches for explaining low-energy heavy-ion reactions. In order to explain the physics behind the reactions, first, we extract the total fusion cross-sections for the 9Be + 208Pb system by using the coupled channel method in which both projectile and target excitations can be included. Also, for a more intuitive understanding, we introduce the optical model method and apply it to the elastic scattering for the 11Be+64Zn system when 11Be nuclei are weakly-bound neutron-rich nuclei. The Coulomb dipole excitation and the long-range nuclear potentials turn out to be effective for describing the heavy-ion reactions for neutron-rich nuclei. Finally, we introduce a nuclear reaction experiment that can be performed using the RAON accelerator.
