Density distribution effect on the analysis of the 6Li+ 58Ni reaction

Abstract

The effect of density variation on the optical-model (OM) analysis of ⁶Li + ⁵⁸Ni is investigated by using bare potentials extracted from different density distributions of the weakly-bound ⁶Li nucleus. For each of the bare potentials, the real and imaginaru parts of the direct-reaction and fusion polarization potentials are deduced from respective X² fittings to the elastic scattering and fusion data. The results obtained show that variations in the density distribution of the weakly-bound projectile can change the strengths of the dynamic direct-reaction polarization potential, however, it cannot make a noticeable difference on the OM predictions of fusion cross sections.
