Nuclear models in FLUKA: Present capabilities, open problems, and future improvements

Abstract

The nuclear reaction models embedded in the FLUKA code cover hadron, ion, photon and neutrino induced nuclear interactions from energies as low as few tens of MeV up to several tens of TeV. A short description of the main physics ingredients in the FLUKA nuclear models is given, with emphasis on the intermediate energy range and on "exotic" reactions. The treatment of electromagnetic dissociation as recently implemented in FLUKA is described. Examples of performances are presented for illustrative situations covering some of the most typical FLUKA applications. © 2005 American Institute of Physics.
