Computational study of fragmentation cross-sections for 28Si ions in various media using GEANT4.

• Fragmentation cross-section of 28Si ions is calculated using GEANT4 toolkit. • Validation of Geant4 models for computational study of fragmentation cross-section is performed. • C, Al, Cu, Pb and Sn are used as target materials for high energy range of incident 28Si ion beam. • The BIC, the QMD and the INCL models are used for fragmentation cross-section studies and comparison with experimental data. • The good agreement is observed between computational and experimental results. The comparison of simulated data with experimental results is needed for the accuracy and reliability of the transport codes. In this work, we performed a comparative study of simulated results of projectile fragmentation cross-sections (PFXS) for three different models. The obtained results also compared with published experimental data. For simulation purposes, the GEANT4 simulation toolkit based on the Monte Carlo (MC) codes is used. The models in Geant4 employed to compute the PFXS are the Binary Cascade (BIC), the Quantum Molecular Dynamics (QMD), and the Intranuclear cascade (INCL). In the present study we reported the interaction of 28Si ion beam for the energy range 270–1200 A MeV incident on carbon (C), aluminium (Al), copper (Cu), tin (Sn), and lead (Pb) targets. The QMD, the BIC, and the INCL model coupled with the de-excitation models reproduce the results in agreement with experimental fragmentation cross-sections. [ABSTRACT FROM AUTHOR]
