A DYNAMICAL MODEL FOR MULTIFRAGMENTATION OF NUCLEI

A schematic model based on molecular dynamics and a restructured aggre gation model is presented. We apply it to study the O-16 + Br-80 syste m at several bombarding energies and compare some of the results to av ailable emulsion data. We find that the model reproduces the experimen tal charge distributions rather well and the onset of multifragmentati on for this system. Some general features of nuclear multifragmentatio n related to charged-particle production and intermediate-mass-fragmen ts production are discussed.
