STRONG ABSORPTION AND THE DOUBLE FOLDING MODEL 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 plot 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-section of  within the energy range of .
