Analyses of quasielastic scattering data for the $$^{11}$$ 11 Be + $$^{197}$$ 197 Au system

Within the framework of an optical model, the quasielastic channel experimental data for the $$^{11}$$ Be + $$^{197}$$ Au system measured at energies below and around the Coulomb barrier are analyzed. For the analysis of the $$^{11}$$ Be + $$^{197}$$ Au system, we include Coulomb dipole excitations and long-range nuclear potential to account for a long-range effects of this halo nuclear system. Using the parameters obtained from $$\chi ^{2}$$ analysis, we successfully reproduce the quasielastic experimental angular distributions for the $$^{11}$$ Be + $$^{197}$$ Au system.
