Correlation between balance energy and transition energy for symmetric colliding nuclei

TL;DR

This study investigates the relationship between balance energy and transition energy in heavy-ion collisions, revealing how these energies depend on system size, fragment mass, and impact parameter, with reduced cross-section explaining experimental data.

Contribution

It establishes a correlation between transition energy and balance energy, showing their difference decreases with increasing total mass of colliding nuclei, using an isospin-dependent quantum molecular dynamics model.

Findings

Transition energy depends on fragment size, system mass, and impact parameter.

Reduced cross-section explains experimental observations.

Difference between transition and balance energy decreases with system mass.

Abstract

We study the correlation between balance energy and transition energy of fragment in heavy-ion collisions for different systems at incident energies between 40 and 1200 MeV/nucleon using an isospin-dependent quantum molecular dynamics model. With increasing incident energy, the elliptic flow shows a transition from positive (in-plane) to negative (out-of-plane) flow. This transition energy is found to depend on the size of fragments, composite mass of reacting system, and the impact parameter of reaction. It has been observed that reduced cross-section can explain the experimental data. There is a correlation between transition energy and balance energy as their difference decreases with increase in the total mass of colliding nuclei.
