Comparative study of depth dose-distributions and partial fragmentation cross sections of 56Fe ions on polyethylene using GEANT4

Abstract

The depth dose-distributions and partial fragmentation cross sections for 56Fe ions on a polyethylene medium are estimated using Geant4: a Monte Carlo simulation toolkit. The models employed in the present work are the Binary Cascade, Abrasion-Ablation and Quantum Molecular Dynamics. The multifragmentation models, such as statistical multifragmentation and Fermi break-up models are used in combination with the other models to define the nuclear interactions more precisely. The partial fragmentation cross sections are calculated on the basis of charge scored in the detector. The simulated results are validated by comparing with the experimental data.
