Glauber-Model-Based Computational Evaluation of ³¹Ne Differential Cross Sections for Exploring Halo Phenomena in Neon Nuclei

Abstract

One-nucleon removal cross section of ³⁰Ne core fragment from ³¹Ne + ¹²C reaction system was computed as a sum of the elastic and inelastic reaction cross sections in the frame work of the Glauber Theory using the CSC_GM code. The neon nucleus   which consists of ten protons and twenty one neutrons having a low binding energy is expected to be a neutron halo candidate. The projectile nucleus is assumed to have ³⁰Ne + ¹n structure. Both the contributions from the elastic and inelastic reaction cross sections were shown. The contribution from the inelastic break up cross section is much larger than that from the elastic cross section in the energy region beyond a few hundred MeV per nucleon, the wide gap between () and () and also the large nucleon removal cross section of 137.32mb at projectile energy of 900MeV suggest ³¹Ne to have a neutron halo structure. Which are found to agree with the experimental data.
