A unique deep potential for the 16O+16O system

We have reanalysed the recently observed nuclear rainbow data for the 16O+16O system and have demonstrated that there are three optical potentials which fit the data equally well. This discrete ambiguity originates from the limited angular range of the data. By taking into account the results of a recent analysis of low-energy resonant phenomena in this system and the dispersion relation between the real and imaginary parts of the optical potential, a unique selection of the potential set can be made.
