Measurement and evaluation of fragmentation cross-sections of intermediate energy heavy ions

对重离子治疗和载人航天任务中重要的原子核在10 - 1000 MeV/u能量范围内的破碎截面进行了测量。测量了Pb（C,x）、C（C,x）和C（Al,x）反应的截面，作为反应能量的函数。在本研究中，开发了测量这些截面的新方法，并将测量的截面用于基准辐射输运模拟程序PHITS，以改进其反应模型。本研究采用统计多碎片模型和修正的量子分子动力学模型。

Fragmentation cross-sections in the energy range from 10 to 1000 MeV/u of nuclei important for heavy ion therapy and manned space missions were measured. The cross-sections were measured in Pb(C,x), C(C,x) and C(Al,x) reactions as functions of reaction energy. In this study, novel methods to measure these cross-sections were developed and the measured cross-sections were used to benchmark radiation transport simulation code PHITS to improve its reaction models. The statistical multi-fragmentation model and revised quantum molecular dynamics model were implemented in this study.
