Elastic scattering of heavy ions and nucleus-nucleus potential with a repulsive core

V. Yu. Denisov, O. I. Davidovskaya

Abstract

Elastic scattering of 12 C + 12 C at 139.5, 158.8 MeV and 16 O + 12 C at 132, 169 MeV was analyzed in the framework of an optical model using the repulsive-core nucleus-nucleus potential. Calculations with and without consideration of the core were performed and the influence of the core on the elastic scattering cross section was analyzed. It was shown that taking account of the core leads to an increase in the elastic scattering cross section for backward angles. The decomposition of the scattering amplitude into nearside and far-side components was studied.
