Abstract
A nonlocal optical model program has been written in order to investigate the effects of Gaussian nonlocal potentials on heavy-ion scattering and reactions. We have tested the two principal approximations which have been used to handle nonlocal effects in light-ion reactions, the Perey-Buck nonlocal-to-local potential transformation and the local-energy approximation. We find that both of these approximations work very well for the heavy-ion reactions studied up to nonlocal ranges of about $\ensuremath{\beta}=0.4$ fm, but fail for larger ranges. Using the local-energy approximation we have tested the sensitivity of distorted-wave Born-approximation calculations to the nonlocal range $\ensuremath{\beta}$. For strongly absorbing potentials, values of $\ensuremath{\beta}\ensuremath{\gtrsim}0.4$ fm cause negligible effects while weakly absorbing potentials with $\ensuremath{\beta}=0.4$ fm allow strong modifications to the predicted cross sections.NUCLEAR REACTIONS Effects of nonlocal optical potentials in heavy-ion scattering and reactions, exact nonlocal optical model calculations, tested approximations to nonlocal effects, nonlocal DWBA calculations.
