This work contains a theoretical study to find the signature of liquid gas phase transition in the collision of 197Au+197Au at incident energies between 20-1000 MeV/nucleon and at impact parameters b = 0, 4, 8, and 12 fm. The Quantum Molecular Dynamics (QMD) model was used to generate the phase-space of nucleons. The phase-space was, then, analyzed using different clusterization procedures. a systematic study of the charge yield dN/dZ as a function of charge of fragments was carried out in collision of 197Au+197Au at incident energies between 20-1000 MeV/nucleon and at different colliding...
