A MICROCANONICAL MODEL OF HOT NUCLEI

We describe our Metropolis Monte Carlo computer code for the microcano nical calculation of the fragmentation of a hot nucleus. It is applica ble for nuclei with excitation energies on the order of 1-20 MeV per n ucleon, such as might be created in intermediate-energy heavy-ion coll isions. The code creates complete, individual events in which both ene rgy and mass are exactly conserved, and will write the individual even ts as well as perform analyses. The events are created by sampling the phase space available to the fragmenting nucleus, visiting each cell in phase space in proportion to its statistical weight.
