AI中文摘要：
本文提出了一种新的解析框架，命名为JO\&Minna方法，用于解释重离子束在厚结构材料中诱导的残余活化的深度分布。通过结合极限碎裂和因子化原理，JO因子形式严格地将弹丸类碎片的空间分布与射程导数和电子阻止本领联系起来。此外，Minna程序通过剖面微分和卷积分析建立了数学联系，以从测量的活化剖面重建碎片的原始能谱和能量展宽。该方法使用$^{238}$U辐照铝中产生$^{46}$Sc的实验数据进行基准测试，展示了在加速器材料研究中提取碎片产生运动学和能量分布的可靠且直接的方法。
英文摘要：
A novel analytical framework, designated as the JO\&Minna method, is presented for interpreting the depth profiles of residual activation induced by heavy-ion beams in thick structural materials. By combining the limiting fragmentation and factorization principles, the JO-factor formalism rigorously links the spatial distribution of projectile-like fragments to the range derivatives and electronic stopping powers. Furthermore, the Minna procedure establishes a mathematical link via profile differentiation and convolution analysis to reconstruct the original energy spectrum and energy spread of the fragments from the measured activity profiles. The methodology is benchmarked using experimental data for $^{46}\text{Sc}$ production from $^{238}\text{U}$ irradiation in aluminum, demonstrating a reliable and straightforward approach for extracting fragment production kinematics and energy distributions in accelerator materials research.
