Abstract
An analytical expression to evaluate the dispersive contribution to the rea l potential for complicated energy and radial shape dependences of the empi rical imaginary part is presented and applied to O-16-O-16 at intermediate energies. The calculated dispersive potentials describe the general feature s of the measured angular distributions and the energy dependence of the vo lume integrals. The best agreement with the elastic scattering data is obta ined when the imaginary part is simplified to consist only of a volume term . (C) 2001 Elsevier Science B.V. All rights reserved.
