Mass dependence of various fragments in multi-fragmentation

TL;DR

This study uses the IQMD model to analyze how target mass affects fragment production in heavy-ion collisions, revealing a correlation with impact parameter and partial agreement with experimental data.

Contribution

It investigates the influence of target mass on fragmentation in heavy-ion collisions using IQMD simulations, highlighting the impact parameter dependence.

Findings

Fragment production varies with target mass and impact parameter.

Results align with experimental data at lower impact parameters.

Some deviations occur at higher impact parameters.

Abstract

Based on the isospin-dependent quantum molecular dynamics (IQMD) model, we aim to understand the effect of target fragmentation on various quantities i.e. collision rate, fragments multiplicity etc by simulating the collision between $Au^{197}$ projectile and $C^{12}$, $Al^{26}$, $Cu^{63}$, and $Pb^{208}$ as targets at incident energy 600 MeV/nucleon. The collision geometry is varied from central to peripheral. Our results indicate the rise and fall in the production of intermediate mass fragments with ${Z_{bound}}$ which is in agreement with the experimental data of Aladin collaboration at lower impact parameters, while, some deviation is seen at higher impact parameters.
