Isospin effects on the energy of vanishing flow in heavy-ion collisions

TL;DR

This study uses an isospin-dependent quantum molecular dynamics model to analyze how isospin influences the energy at which collective flow vanishes in heavy-ion collisions, aligning well with experimental data.

Contribution

It demonstrates the effectiveness of the isospin-dependent quantum molecular dynamics model in accurately predicting the energy of vanishing flow across different collision geometries.

Findings

Model predictions agree with experimental data within 5% for central collisions.

Model predictions agree with experimental data within 10% for peripheral collisions.

Isospin effects significantly influence the energy of vanishing flow.

Abstract

Using the isospin-dependent quantum molecular dynamics model we study the isospin effects on the disappearance of flow for the reactions of $^{58}Ni$ + $^{58}Ni$ and $^{58}Fe$ +$^{58}Fe$ 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) geometries.
