A Geant4 physics list for spallation and related nuclear physics applications based on INCL and ABLA models

Abstract

A new Geant4 physics list is prepared for nuclear physics applications in the domain dominated by spallation. The C++ translation of original Fortran INCL intra-nuclear cascade and ABLA fission/de-excitation codes are used in the physics list. The INCL model prepared is well established for targets heavier than Aluminium and projectile energies from 150 MeV up to 2.5 GeV - 3 GeV. Validity of the new Geant4 physics list is demonstrated, and the neutron double differential cross sections and residual nuclei production discussed. Foreseen improvements of the physics models for the treatment of light targets (Carbon - Oxygen) and light ion beams (up to Carbon) are discussed. © 2010 IOP Publishing Ltd.
