Nuclear reaction stopping of 400 MeV/nucleon 56Fe in water

Geant4 toolkit for Monte Carlo simulation is used in high energy heavy ion energy deposition simulation. The energy deposit of relativistic 400 MeV/nucleon Fe-56 has contributions from three sources, namely electronic stopping, nuclear stopping and nuclear reaction stopping. The electronic stopping and nuclear stopping are well known ionization, excitation and elastic collision of particles, the nuclear reaction stopping comes from the contribution of secondary particles emitted from nuclei during nuclear reaction. Yields of secondary particles induced by relativistic Fe-56 in water and the energy deposited near the track are calculated.
