The heavy-ion nuclear potential: determination of a systematic behavior at the region of surface interaction distances

CP Silva, MAG Alvarez, LC Chamon, D Pereira… - Nuclear Physics A, 2001 - Elsevier
Precise elastic scattering differential cross sections have been measured for the 16O+
120Sn, 138Ba, 208Pb systems at sub-barrier energies. The corresponding “experimental”
nuclear potentials have been determined at interaction distances larger than the Coulomb
barrier radii. These experimental potentials have been compared with our earlier results for
other systems, and with theoretical calculations based on the double-folding and liquid-drop
models. We have shown that the nuclear potentials have a systematic behavior at the …
