Phenomenological and Semi-microscopic Analysis for the Elastic Scattering of Protons from ¹²C Nuclei at Different Energies

Abstract

Analysis of the elastic scattering of protons from 12 C nuclei had been performed within the framework of both the optical model and single folding model at different proton energies; 17, 30.3, 40, 49.48 and 61.4 MeV. We have obtained the global potential parameters which could fairly reproduce the experimental data for p+ 12 C elastic scattering at the aforementioned energies. The radial and energy dependence of the real and imaginary parts of the potential w ere calculated. Good agreement between experimental data and theoretical predictions in the whole angular range was obtained using both phenomenological approach (Optical Model), and semi-microscopic approach (Single Folding). In single folding calculations, the real part of the potential was calculated from a more fundamental basis by the folding method in which the NN interaction V NN ( r ), is folded into the density of the target nuclei and supplemented with a phenomenological imaginary potential. The obtained normalization factor N r is in the range of 0.75 - 0.9.
