Reconstructed neutron magnetic structure via selective flattening: Insights from Patterson function analysis

This study introduces a novel reconstruction of the neutron’s internal magnetic structure, achieved through a selective flattening method applied to Patterson function analysis. By adjusting the radial Patterson magnetization density to match experimental observations, we obtain a finely resolved spatial distribution that unveils the neutron’s internal features with exceptional clarity. The resulting magnetization profile reveals a pronounced core-shell arrangement: a dense, sharply defined positive central core reaching 1525 fm⁻³, surrounded by a broad, gently negative shell with a minimum of −51.4 fm⁻³. Developed without reliance on theoretical models, this data-driven approach offers a fresh and unbiased framework for exploring subatomic magnetization patterns.本研究提出了一种全新的中子内部磁结构重建方法，通过将选择性平化方法应用于帕德森函数（Patterson function）分析得以实现。通过调整径向帕德森磁化密度以匹配实验观测结果，我们获得了高分辨率的空间分布，能够极其清晰地揭示中子的内部结构特征。所得磁化分布呈现出显著的核-壳结构：致密且边界清晰的正性中心核，其磁化密度峰值可达1525 飞米⁻³，周围被一片宽阔且平缓的负性壳层包裹，该壳层的最小磁化密度为−51.4 飞米⁻³。该方法无需依赖理论模型，而是采用数据驱动的思路，为探索亚原子磁化模式提供了全新且无偏的研究框架。
