A method for identifying statistical equilibrium stages in dynamical multifragmentation paths as provided by transport models, already successfully tested for the reaction 129Xe+119Sn at 32 MeV/nucleon is applied here to a higher energy reaction, 129Xe+119Sn at 50 MeV/nucleon. The method evaluates equilibrium from the point of view of the microcanonical multifragmentation model (MMM) and reactions are simulated by means of the stochastic mean field model (SMF). A unique solution, corresponding to the maximum population of the system phase space, was identified suggesting that a huge part of the available phase space is occupied even in the case of the 50 MeV/nucleon reaction, in presence of a considerable amount of radial collective flow. The specific equilibration time and volume are identified and differences between the two systems are discussed.
