Nucleus-nucleus potential within the semimicroscopic dispersive model on the basis of a corrected folding-model potential

A procedure is proposed for correcting the energy dependence of the mean-field component of the optical-model potential, this component being calculated within the double-folding model with allowance for exchange effects in the approximation of one-nucleon knockout exchange. The procedure is based on employing, for the mean field, an empirical energy dependence that is obtained from a dispersion analysis of integrated features of phenomenological optical-model potentials and is tested by applying it to calculating the mean field and to analyzing data on the elastic scattering of alpha particles on oxygen nuclei within the semimicroscopic dispersive optical model
