Model for projectile fragmentation: Case study for Ni on Ta and Be, and Xe on Al

Abstract

For projectile fragmentation, we work out details of a model whose origin can be traced back to the Bevalac era. The model positions itself between the phenomenological empirical parametrization of fragmentation cross sections (EPAX) and microscopic transport models like the heavy ion phase-space exploration (HIPSE) model and antisymmetrized molecular dynamics (AMD) model. We apply the model to some recent data of projectile fragmentation of Ni on Ta and Be at beam energy 140 MeV/nucleon and some older data of Xe on Al at beam energy 790 MeV/nucleon. Reasonable values of cross sections for various composites populated in the reactions are obtained.
