Extended optical model analyses of with dynamic polarization potentials

We discuss angular distributions of elastic, inelastic, and break-up cross-sections for the system, measured at energies below and around the Coulomb barrier. To this end, we employ Coulomb dipole excitations and a long-range nuclear (LRN) potential in order to account for long-range effects of the halo nuclear system and break-up effects of the weakly bound structure. We then analyze recent experimental data, comprising three channels, viz., elastic, inelastic, and break-up cross-sections, at and . From the parameter sets extracted using a analysis, we successfully reproduce the experimental angular distributions of the elastic, inelastic, and break-up cross-sections for the system simultaneously. Finally, we discuss the necessity of the LRN potential around the Coulomb barrier from a detailed analysis of the experimental data.
