A parameter-free optical potential for the heavy-ion elastic scattering process Original Research Article

Thirty elastic scattering angular distributions for seven heavy-ion systems, in wide energy ranges, have been studied with the aim of systematizing the optical potential, real and imaginary parts, in a global way. The framework is: (i) an extensive systematization of nuclear densities, (ii) the energy dependence of the bare potential accounted by a model based on the nonlocal nature of the interaction, and (iii) the real and imaginary parts of the optical potential assumed to have the same radial shape.
