SEARCHING FOR THE NUCLEAR LIQUID-GAS PHASE-TRANSITION IN AU+AU COLLISIONS AT 35 MEV NUCLEON/

Within the framework of classical molecular dynamics, we study the col lision Au+Au at an incident energy of 35 MeV/nucleon. It is found that the system shows a critical behavior at peripheral impact parameters, revealed through the analysis of conditional moments of charge distri butions, Campi scatter plot, and the occurrence of large fluctuations in the region of the Campi plot where this critical behavior is expect ed. When applying the experimental filters of the MULTICS-MINIBALL app aratus, it is found that criticality signals can be hidden due to the inefficiency of the experimental apparatus. The signals are recovered by identifying semiperipheral and peripheral collisions looking to the velocity distribution of the largest fragment, and selecting the most complete events.
