Abstract

Abstract Entropy per nucleon has been extracted for the Au (150–800 A MeV) + Au reaction measured at GSI by using the 4π-Facility (Phase I). The entropies were obtained from the comparison of various observables (multiplicities and average charge) with predictions of the Quantum Statistic Model. These entropies are found somewhat lower than an earlier determination and in good agreement with hydrodynamical calculations, they suggest low viscosity for nuclear matter.
