DENSITY-DEPENDENT EFFECT ON ALPHA-C-12 ELASTIC-SCATTERING

An analytical expression for the real part of the folding potential, using a density-dependent effective interaction, is derived by taking the density of the C-12 nucleus according to Brink's alpha-particle model. The present model has succeeded, particularly at large angles, in describing the rainbow scattering observed in the elastic scattering of alpha-particles by C-12 at the energies 104, 139 and 166 MeV respectively. The density-dependent parameter beta is found to be energy independent.
