Dependence of balance energy on isospin degrees of freedom

TL;DR

This study uses an isospin-dependent quantum molecular dynamics model to analyze how isospin influences the disappearance of flow in specific nuclear reactions, matching experimental data closely across different collision geometries.

Contribution

It demonstrates the effectiveness of the isospin-dependent quantum molecular dynamics model in accurately predicting the energy of vanishing flow in nuclear reactions.

Findings

Good agreement with experimental data across all geometries

Reproduces data within 5% at central collisions

Reproduces data within 10% at peripheral collisions

Abstract

Using the isospin-dependent quantum molecular dynamics model we study the isospin effects on the disappearance of flow for the reactions of 58Ni+58Ni and 58Fe+58Fe as a function of impact parameter. We found good agreement between our calculations and experimentally measured energy of vanishing flow at all colliding geometries. Our calculations reproduce the experimental data within 5%(10%) at central (peripheral) colliding geometries.
