Surface effect in explaining the elastic scattering of the+12C system at lowenergies

Özet

In this paper, the elastic scattering angular distributions data of the+12C reaction at an energy rangeof 13.0 to 172.5 MeV were analyzed within the framework of optical model formalism. A phenomenological deep realpotential was used with a phenomenological Woods{Saxon type imaginary potential. Excellent agreement was obtainedin the high-energy region. The phenomenological deep potential was unable to explain the experimental data in thelow-energy region. The experimental data at both low and high energies could not be explained at the same time. Inorder to explain the data simultaneously at low energy and high energy, the shape of the deep real potential was modi edin the surface region. This work shows the role of the surface region of two nuclei in explaining the elastic scatteringdata of this system.
