Zusammenfassung:In this work we present optical model analysis of new near barrier-quasi-elastic experimental data, for the systems (6,7)Li +(120)Sn. From the analysis it was possible to extract the ground state nucleon densities of the weakly bound (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 (6,7)Li states of the continuum.
