The dispersion relation applied to the radial shape and energy dependence of the 16O–16O potential at intermediate energies Original Research Article

An analytical expression to evaluate the dispersive contribution to the real potential for complicated energy and radial shape dependences of the empirical imaginary part is presented and applied to 16O–16O at intermediate energies. The calculated dispersive potentials describe the general features of the measured angular distributions and the energy dependence of the volume integrals. The best agreement with the elastic scattering data is obtained when the imaginary part is simplified to consist only of a volume term.
