Findings

Nuclear stopping decreases with stiffer symmetry energy (larger gamma).

Nuclear stopping is sensitive to the form of density-dependent symmetry energy.

The study uses a soft equation of state with reduced isospin-dependent cross-section.

Abstract

The effect of density dependent symmetry energy on nuclear-stopping is studied using isospin-dependent quantum molecular dynamics model(IQMD). We have used the reduced isospin-dependent cross-section with soft(S) equation of state for the systems having different isostopic content, to explore the various aspects of nuclear stopping. The aim is to pin down the nature of the nuclear stopping with density dependent symmetry energy. Nuclear stopping is found to be sensitive towards the various forms of the density dependent symmetry energy. The nuclear stopping tends to decrease for the stiffer equation of state (EOS), i.e. larger values of gamma.
