In this work we present optical model analysis of new near barrier-quasi-elastic experimental data, for the systems {sup 6,7}Li+{sup 120}Sn. From the analysis it was possible to extract the ground state nucleon densities of the weakly bound {sup 6,7}Li isotopes. The apparent discrepancies between the experimental densities, as compared with those based on Dirac-Hartree-Fock-Bouguliubov (DHB) calculations were removed, considering in the reaction mechanism, the projectile break-up and a positive polarization from couplings of {sup 6,7}Li states of the continuum.
