Folding model analysis of alpha-particle elastic scattering with a semirealistic density dependent effective interaction

Technical Report ·

; ; ; ;

The aim of this study was to examine the density dependent effective interaction, DDEI, applied in the double-folding model and to investigate whether folding model analyses of alpha particle elastic scattering could be used to calculate nuclear matter densities. Accordingly, differential cross-sections for the elastic scattering of alpha particles from (40)Ca, (46,48,50)Ti, (58)Ni, (90)Zr and (208)Pb at 140 MeV and from (58,60,62,64)Ni at 172 MeV were analyzed using the model with a semirealistic DDEI based on the M3Y interaction for the real potential and various phenomenological imaginary potentials. Good fits with consistent parameters of the model were obtained. The application of folding model analyses of alpha particle elastic scattering to the determination of nuclear matter density distribution was critically examined.
