Özet
In this paper, we have analyzed the elastic scattering data of the alpha + C-12 system at 13, 18, 54.1 and 60 MeV incident energies within the framework of the double folding model. We have modified the shape of the real and imaginary parts of the optical potential simultaneously, in the surface region, in order to take into account the effects of the dynamical polarization. With this, we have been able to obtain an improved agreement of the theoretical cross sections with the experimental data. We have also calculated alpha-cluster states in O-16 using the same potential. We have shown that the inclusion of the dynamical polarization potential (DPP) in the bare folding potential provides an improvement also in producing the O-16 rotational bands and corresponding excitation energies. Thus, DPP effect is important in explaining the reaction observables of alpha + C-12 system as well as the structure of the O-16 at low energies (C) 2019 Elsevier B.V. All rights reserved.
