Influence of charge asymmetry and isospin dependent cross-section on elliptical flow

TL;DR

This study uses the isospin dependent quantum molecular dynamics model to analyze how charge asymmetry and isospin-dependent cross-sections influence elliptical flow in nuclear reactions, revealing strong dependence on isospin and consistent experimental agreement.

Contribution

It demonstrates the significant impact of isospin-dependent cross-sections on elliptical flow and provides simulation results aligned with experimental data.

Findings

Elliptical flow depends strongly on isospin of cross-section.

Transition energy remains nearly constant with increasing N/Z ratio.

Simulation results agree well with experimental measurements.

Abstract

Using the isospin dependent quantum molecular dynamics model, we study the effect of charge asymmetry and isospin dependent cross-section on different aspects of elliptical flow. Simulations have been carried out for the reactions of $^{124}X_{m}+^{124}X_{m}$, where m = (47, 50, 53, 57 and 59) and $^{40}X_{n}+^{40}X_{n}$, where n= (14, 16, 18, 21 and 23). Our study shows that elliptical flow depend strongly on the isospin of cross-section. The transition energy remains almost constant with increase in N/Z of the system. A good agreement is obtained with experimental measurements.
