Effects of nonlocal potentials in heavy-ion reactions
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 ..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 ..beta... For strongly absorbing potentials, values of ..beta..approximately-less-than0.4 fm cause negligible effects while weakly absorbing potentials with ..beta..=0.4 fm allow strong modifications to the predicted cross sections.
