THE PRODUCTION OF RESIDUAL NUCLEI IN PERIPHERAL HIGH-ENERGY NUCLEUS-NUCLEUS INTERACTIONS

A formation zone intranuclear cascade model is applied to peripheral n ucleus-nucleus collisions. We calculate the excitation energies of pre fragments, treat their further nuclear disintegration and introduce a model for nuclear deexcitation by photon emission. Results are compare d to data on target associated particle production in nucleus-nucleus collisions. We discuss implications of these models to the description of particle production in the fragmentation regions. Special emphasis is put on applications for air showers induced by cosmic ray nuclei a nd for residual nucleus production at heavy ion colliders.
