The study of participant and spectator matter for asymmetric collisions

Heavy-ion collisions at intermediate energies offer unique possibility to probe the nuclear matter under different conditions of densities and temperature. The breaking of colliding nuclei into several complex pieces has been of core importance both in experimental and theoretical arena. A very useful concept in heavy ion physics is that of spectators and participants. To understand the reaction dynamics, one needs to explore sequentially the mechanisms evolved during the whole time span of the reaction. The present study aims to demonstrate the participant and spectator matter for asymmetric collision i.e. ¹²₆C+¹⁹⁷₇₉Au. All nucleons experiencing at least one collision are labeled as participant matter. The remaining nucleons are the part of spectator matter. In heavy ion systems, when the energy of projectile beam is increased, the spectator part of the projectile is excited due to the migration of some participant part to the spectator part. With increase in the incident energy. This happens because, with increase in incident energy the excitation among the nucleons increases and thus the participant zone expand due to the formation of high density zone, which results in the increase in the collision rate
