Refractive Features and Diffraction Scattering Patterns Observed in the Elastic Scattering of ¹²C from ¹²C at Various Energies

Abstract

We have measured the angular distributions for 12 C ion beam elastically scattered from 12 C target of thickness 17.4 μg/cm 2 at energies 15, 18 and 21 MeV which is close to the Coulomb barrier energy for 12 C + 12 C nuclear system. The elastic scattering of 12 C beam on 12 C was analy s ed also at different energies (139.5, 158.8, 180, 240, 288.6, 300, 360 and 420 MeV) from literature in order to obtain the global optical potential parameters, which could fairly reproduce the experimental data. The experimental results were analysed within the framework of both the optical model and the dou ble folding potential obtained with different density-dependent NN interactions which give the corresponding values of the nuclear incompressibility K in the Hartree-Fock calculation of nuclear matter. The agreement between the experi mental results and the theoretical predictions in the whole angular range is fairly good.
