energies require values of -1 fm for the diffuseness parameter of the Woods-Saxon potential. This is large compared with the values deduced from elastic scattering.
Double folding model calculations of the bare nucleus-nucleus potential have been carried out to predict the *fusion barrier energies and nuclear potential diffusenesses. Both the calculated barrier energies, and equivalent potential diffusenesses at the barrier radii, are generally lower than those found experimentally.
These discrepancies raise questions about both the determination of the bare nucleus-nucleus potential with the folding model, and the boundary of the effects of friction on the fusion process.

Precise elastic scattering differential cross sections have been measured for the 16 O + 120 Sn, 138 Ba, 208 Pb systems at sub-barrier energies. The corresponding "experimental" nuclear potentials have been determined at interaction distances larger than the Coulomb barrier radii. These experimental
