摘要

4He离子在各种材料中诱导二次中子产生的精确模拟对于许多应用是必不可少的。本研究评估了GEANT4、PHITS和FLUKA在计算由4He离子诱导的次级中子的截面和产率方面的性能。仿真结果与实验数据进行了比较，以评估其准确性。PHITS和FLUKA与实验测量结果非常吻合，表明了它们的可靠性。相比之下，使用默认参数的INCL模型的GEANT4模拟明显低估了薄目标和厚目标的中子产量。这种差异可以通过调整INCL模型中的费米动量或使用LIQMD模型来减小。该研究强调了三种代码在模拟中子产生方面的能力和局限性，为它们在辐射屏蔽和核物理研究中的适用性提供了见解。结果表明，三种代码在不同的能量范围和目标材料上具有一定的预测能力。

Calculations of secondary neutron production cross sections and yields induced by high-energy 4He ions

Accurate simulation of secondary neutron production induced by

He ions in various materials is essential for numerous applications. This study evaluates the performance of GEANT4, PHITS, and FLUKA in calculating cross sections and yields of secondary neutrons induced by

^{4}

He ions. The simulation results are compared with experimental data to assess their accuracy. PHITS and FLUKA show strong agreement with experimental measurements, indicating their reliability. In contrast, GEANT4 simulations using the INCL model with default parameters significantly underestimate neutron production for both thin and thick targets. This discrepancy can be reduced by adjusting the Fermi momentum within the INCL model or using the LIQMD model. The study highlights the capabilities and limitations of three codes in modeling neutron production, providing insights into their applicability for radiation shielding and nuclear physics research. The results demonstrate that three codes offer reliable predictions, with specific strengths in different energy ranges and target materials.

期刊介绍： Section B of Nuclear Instruments and Methods in Physics Research covers all aspects of the interaction of energetic beams with atoms, molecules and aggregate forms of matter. This includes ion beam analysis and ion beam modification of materials as well as basic data of importance for these studies. Topics of general interest include: atomic collisions in solids, particle channelling, all aspects of collision cascades, the modification of materials by energetic beams, ion implantation, irradiation - induced changes in materials, the physics and chemistry of beam interactions and the analysis of materials by all forms of energetic radiation. Modification by ion, laser and electron beams for the study of electronic materials, metals, ceramics, insulators, polymers and other important and new materials systems are included. Related studies, such as the application of ion beam analysis to biological, archaeological and geological samples as well as applications to solve problems in planetary science are also welcome. Energetic beams of interest include atomic and molecular ions, neutrons, positrons and muons, plasmas directed at surfaces, electron and photon beams, including laser treated surfaces and studies of solids by photon radiation from rotating anodes, synchrotrons, etc. In addition, the interaction between various forms of radiation and radiation-induced deposition processes are relevant.
