    A phenomenological analysis, based on distances, has been performed for elastic scattering data induced by tightly-bound ( 11 B, 12 C and 16 O), weakly-bound ( 6 Li, 7 Li, 7 Be, 9 Be), and exotic ( 6 He, 8 B, 11 Be, 15 C) nuclei on light ( 27 Al), medium ( 58 Ni and 120 Sn) and heavy mass ( 208 Pb) targets, at energies close to the Coulomb barrier. The cross-section data on the angular distributions have been converted as a function of the distance of the closest approach. From a fitting analysis, critical interaction and strong absorption distances were extracted from the data, and a correlation was observed with the projectile cluster configuration for the data on the target 208 Pb.
