NUCLEAR LIQUID-GAS PHASE-TRANSITION SHOWN IN MULTIFRAGMENTATION

The Incomplete-Fusion-Fragmentation Model has been used to reproduce n icely the experimental evidence of liquid-gas phase transition probed in the reaction of Au + Au at 600A MeV. The analysis of the relative y ields of decay modes for the projectile remnant as a function of [Z(bo und)] shows clearly the competition and transformation processes of va rious decay modes of projectile remnant with decreasing of [Z(bound)] The agreement between theoretical and experimental results for the ana lysis of relative yield of decay modes indicates that the experimental evidence of liquid-gas phase transition is composed of the decay mode transformations.
