Özet

In this paper, we have analyzed the well-known quasielastic scattering data at 29MeV/nucleon of the Li-11+ Si-28 system within the framework of the coupled-channels model using double-folding potential with a Woods-Saxon type of imaginary part. To explain these challenging data, we have modified the shape of the real and imaginary potentials simultaneously in the surface region and we have been able to obtain an improved agreement with the experimental data in comparison with the previous works conducted so far. Our findings confirm that the interactions in the surface region of two nuclei are very important in explaining the scattering observables of such light-heavy nuclei reactions. Our work also shows that the dynamical polarization potential should be attractive for this system.
