New formula for charge change cross section of nucleus-nucleus interaction

Abstract

By including the projectile neutron contribution, we developed a free parameter formula based on the Glauber model framework for nucleus-nucleus interaction to determine the total charge change cross section σ_cc. The formula successfully reproduced the experimental data of reactions ⁹Be + ¹²C, ^16,17O + ¹²C, ²⁷Al + ¹²C, ²⁸Si + ¹²C, ⁴⁰Ar + ¹²C, ⁵⁶Fe + ¹²C, and ²³⁸U + ²⁷Al. Consequently, our study ensures that the charge change cross sections depend on the projectile's neutrons, as well as its protons.
