Phase space analysis of fragmentation and role of mass asymmetry
  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.
