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 imaginary parts of the direct-reaction and fusion polarization potentials are deduced from respective χ2 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.

Keywords : optical model; weakly-bound system; density distribution.
