Phase space analysis and contribution of participant-spectator matter towards fragments formed in heavy-ion collisions

We study the contribution of participant and spectator matter towards different kinds of fragments. We find higher contribution of spectator matter towards heavier fragments compared to lighter fragments. We also notice that heavier IMFs preserve the time correlations. The nucleons emerging as lighter IMFs however, are well separated in the phase space at the start of the reaction and form the cluster at later times. The neutron-richness of the reacting partners is found to have negligible effect on the participant-spectator matter.
