An energy density derived from the relativistic mean-field theory has been used to calculate the real optical potential of ${}_{}{}^{40}{}_{}{}^{}\mathrm{-}_{}^{40}{}_{}{}^{}$Ca nuclei at different energies. We used two sets of mean-field parameters which correctly produce the binding energy and saturation density of nuclear matter. We studied the effect of the relativistic corrections on the real ion-ion potential. It is found that the heavy ion potential calculated using field theory approach agrees well with that derived from nonrelativistic energy density. © 1996 The American Physical Society.
