Isospin effects on the system size dependence of balance energy in heavy-ion collisions

TL;DR

This paper investigates how isospin influences the balance energy in heavy-ion collisions across various system sizes, highlighting Coulomb repulsion as the dominant factor over symmetry energy.

Contribution

It provides new insights into the role of isospin and Coulomb effects on balance energy in heavy-ion collisions for different system sizes.

Findings

Coulomb repulsion mainly causes differences in balance energy between isobaric systems.

Coulomb effects dominate over symmetry energy in determining balance energy.

Balance energy varies with system size and isospin content.

Abstract

We study the effect of isospin degree of freedom on balance energy throughout the mass range between 50 and 350 for two sets of isobaric systems with N/A = 0.5 and 0.58. Our fndings indicate that different values of balance energy for two isobaric systems may be mainly due to the Coulomb repulsion. We also demonstrate clearly the dominance of Coulomb repulsion over symmetry energy.
