Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms ( IF 1.4 ) Pub Date : 2021-05-24 , DOI: 10.1016/j.nimb.2021.05.015

The computational study of projectile range and partial fragmentation cross-section (PFXS) has been executed for 20Ne ion using Geant4 Monte Carlo simulation toolkit. The interaction of heavy semi-symmetric system for energy range 290 MeV/n−670 MeV/n has been researched on various targets: carbon (C), aluminium (Al), copper (Cu), tin (Sn), lead (Pb), and tantalum (Ta). The range simulated via Geant4 and SRIM software shows an agreement of ~ 99%. The PFXS simulation has been conducted using three models of Geant4: the Binary Cascade (BIC), Liege Intranuclear cascade (INCL++), and Quantum Molecular Dynamics (QMD). The PFXS is computed for heavy (Z = 5–9) and light (Z = 2–4) fragments. These models have been validated by analysing simulation data with experimental and semi-empirical nuclear fragmentation model data. The QMD model provides the best data for PFXS following an odd–even effect for all targets. The BIC and the INCL++ behave in similar manner for high Z target.

太空屏蔽和强子疗法应用中各种目标的20 Ne离子范围和碎片截面:蒙特卡洛模拟研究

弹丸射程和局部破碎截面(PFXS)的计算研究已经进行了20次使用Geant4蒙特卡罗模拟工具包。能量范围为290 MeV / n−670 MeV / n的重半对称系统之间的相互作用已针对各种目标进行了研究:碳(C),铝(Al),铜(Cu),锡(Sn),铅(Pb )和钽(Ta)。通过Geant4和SRIM软件模拟的范围显示约99%的一致性。使用Geant4的三种模型进行了PFXS模拟:二进制级联(BIC),列日核级联(INCL ++)和量子分子动力学(QMD)。PFXS是针对重碎片(Z = 5–9)和轻碎片(Z = 2–4)计算的。这些模型已经通过使用实验和半经验核碎裂模型数据分析模拟数据进行了验证。在对所有目标产生奇偶效应后,QMD模型可为PFXS提供最佳数据。
