Phase space analysis of fragmentation and role of mass asymmetry

TL;DR

This paper uses quantum molecular dynamics to analyze how different fragments form in symmetric and asymmetric heavy-ion collisions at 200 MeV/nucleon, emphasizing the role of fragmentation criteria in participant and spectator matter.

Contribution

It introduces a detailed phase space analysis of fragmentation processes in heavy-ion collisions, highlighting the significance of mass asymmetry and fragmentation criteria.

Findings

Light mass fragments are part of participant matter.

Intermediate mass fragments originate from spectator regions.

Fragmentation criteria are crucial for understanding fragment formation.

Abstract

Based on the quantum molecular dynamics (QMD) picture, we aim to understand heavy-ion collisions in terms of participant spectator matter leading to various fragments of different sizes. The study is performed for symmetric as well as asymmetric reaction at E = 200 MeV/nucleon for central collisions. Our results highlight the importance of fragmentation criterion in terms of light mass fargments which are a part of participant matter and intermediate mass fragments which are coming from the spectator region.
