Statistical calculation of complete events in medium-energy nuclear collisions

The essential tools for formulating a statistical model for the nuclear disassembly process are presented. The quick disassembly (explosion) of a hot nuclear system, a so called source, into multifragment final states, which compete according to their statistical weight is considered. First some useful notation is introduced. The expressions for exclusive and inclusive distributions are given and the factorization of an exclusive distribution into inclusive ones is carried out. In turn, the grand canonical approximation for one fragment inclusive distributions is introduced. Finally, it is outlined how to generate a statistical sample of complete final states. On this basis, a model for statistical simulation of complete events in medium energy nuclear collisions was developed.
