The study of multifragmentation around transition energy in intermediate energy heavy-ion collisions

TL;DR

This study investigates how fragment production in intermediate energy heavy-ion collisions varies with incident energy, system size, and impact parameter, revealing no direct link between transition energy and light particle production.

Contribution

It applies the isospin dependent quantum molecular dynamics model to analyze fragmentation trends across a wide energy range, highlighting the independence of light particle production from transition energies.

Findings

Fragment production depends on incident energy, fragment size, and system mass.

No correlation found between transition energy and light charged particle production.

Fragment trends vary with impact parameter and system size.

Abstract

Fragmentation of light charged particles is studied for various systems at different incident energies between 50 and 1000 MeV/nucleon. We analyze fragment production at incident energies above, below and at transition energies using the isospin dependent quantum molecular dynamics(IQMD) model. The trends observed for the fragment production and rapidity distributions depend upon the incident energy, size of the fragments, composite mass of the reacting system as well as on the impact parameter of the reaction. The free nucleons and light charged particles show continous homogeneous changes irrespective of the transition energies indicating that there is no relation between the transition energy and production of the free as well as light charged particles.
