Theoretical interpretation of data obtained in high energy nuclear collisions. Progress report, January 1-December 31, 1986

Data obtained in nuclear collisions at energies ranging from medium to relativistic are interpreted theoretically. The major objective is to connect the observed final state of the collision to the earlier, hot and dense stages of the evolution of the system. Statistical models and the FREESCO event generator are the most important tools used in the project. Exclusive data on central collisions from the Plastic Ball are utilized in an attempt to infer the properties of the nuclear systems at breakup. We try to extract the temperature, density, entropy and the amount of collective motion at breakup. The equation of state of nuclear matter is studied in the excluded volume approximation. Study also centers on the relation of different statistical models. Neutron-proton differencs are analysed and Coulomb final state interactions are investigated in support of experimental projects. Possible scenarios for new experiments are examined
