Effect of isospin dependent cross-section on nuclear stopping

TL;DR

This paper investigates how isospin-dependent cross-sections influence nuclear stopping in heavy ion collisions, using rapidity distribution and nucleon momentum asymmetry to understand reaction outcomes.

Contribution

It introduces an analysis of the impact of isospin-dependent cross-sections on nuclear stopping, expanding understanding beyond previous studies that focused on system size and energy.

Findings

Heavier systems exhibit higher nuclear stopping at all energies.

Radial flow correlates with the degree of nuclear stopping.

Isospin dependence significantly affects collision dynamics.

Abstract

Nuclear stopping in heavy ion collisions (HIC) has been studied by means of rapidity distribution and asymmetry of nucleon momentum distribution. It is an important quantity in determining the outcome of a reaction. Fen Fu {\it et al.,} \cite{2} calculate both the radial flow and the degree of nuclear stopping in Pb + Pb and Ni + Ni at 0.4, 0.8 and 1.2 GeV/neucleon. They found that the expansion velocity as well as the degree of nuclear stopping are higher in the heavier system at all energies.
