Theoretical interpretation of data from high-energy nuclear collisions: Progress report for the period January 1, 1986-July 31, 1987

Technical Report ·
OSTI ID:6231473
The main thrust of this research project have been the production of a sufficiently realistic and sufficiently fast event generator and is connected to the application of this background calculation to the analysis of data and to the design of new experiments in the field of high-energy heavy ion reactions. The microcanonical event generator which has been produced is named FREESCO (FRagmentation in an Explosion/Evaporation Simulation COde). Entropy values from data on central collisions have been extracted for Ca + Ca reactions at 400 MeV/neutron and 1050 MeV/nucleon and Nb + Nb reactions at 400 MeV/nucleon and 650 MeV/nucleon and for both reactions at beam energies on the order of 100 MeV. It was also found that the entropy can be determined approximately uniquely above 90 MeV/nucleon in the Ar + Ca system, independent of the assumed breakup temperature and density. One of the primary goals of colliding nuclei at high energies is to learn about the equation of state of nuclear matter. Research is continuing in this project on obtaining an equation of state at the temperatures and densities obtained in high-energy heavy ion collisions.
