Strong Absorption and The Double Folding Potential Using B3Y-Fetal Interaction

Abstract

This work examines the effects of strong absorption arising from nuclear
potentials which are crucial to the understanding of the problem of nuclear
interactions in other nonelastic channels. The double folding model was
used to derive both the real and imaginary part of the nuclear optical
potential using a mass-dependent B3Y-Fetal effective interaction
constructed using the lowest order constrained variational (LOCV)
approach. The absorption effect was incorporated in the calculations
through the imaginary part of the optical potential. The folded potentials
were found to be attractive and short-ranged over short internuclear
distances of about . The results of the plots of the S-matrix
elements and those of the differential cross-sections of deuteron scattering
from were obtained. It was observed from the plots of the S-matrix
elements that regions for which existed between within the
incident energies of , implying strong absorption at these small
impact parameters. Pronounced success was also achieved in the fit of the
differential cross-sections of within the energy range of
