Possible Form for theLi6-Li6Optical Potential

It is shown that the potential obtained by folding a nucleon-nucleon interaction into the ion densities gives a good description of the real part of the optical potential for ${}_{}{}^6{}_{}{}^{}\mathrm{Li}$-${}_{}{}^6{}_{}{}^{}\mathrm{Li}$ scattering between 9- and 16-MeV center of mass. Some evidence is found for an additional repulsive term at lower energies.
