Abstract

This work explores the gamma-ray shielding properties of different pyroxene crystals (XY(Si,Al)2O6; X, Y = cations), focusing on clinopyroxenes and orthopyroxenes. The shielding parameters, including the MAC, LAC, and Z_eff, were evaluated using structural and compositional data. Clinopyroxenes, such as Hedenbergite (density = 3.56 g/cm³, MAC = 1.002 cm²/g, Z_eff = 20.62) and Aegirine (density = 3.55 g/cm³, MAC = 1.107 cm²/g, Z_eff = 21.66), exhibit superior shielding capabilities, particularly at low photon energies. Orthopyroxenes, such as Ferrosilite (density = 3.25 g/cm³, MAC = 0.999 cm²/g, Z_eff = 20.72) and Hypersthene (density = 3.50 g/cm³, MAC = 0.699 cm²/g, Z_eff = 17.67), offer competitive performance in specific scenarios. The study highlights the critical role of density, atomic packing, and anion-cation radii ratios (R_AC = 0.429−1.143) in determining radiation attenuation. Structural compactness, as revealed by Hirshfeld surface analysis, further enhances γ-ray shielding properties. These findings underscore the potential of pyroxenes as advanced shielding materials for high-energy environments, with applications in optical and electronic fields.

辉石晶体屏蔽伽马射线的结构和拓扑研究

本文探讨了不同辉石晶体(XY(Si,Al)2O6；X, Y =阳离子)，重点是斜辉石和正辉石。使用结构和成分数据评估屏蔽参数，包括MAC、LAC和Zeff。斜辉石，如hedenberite（密度= 3.56 g/cm3, MAC = 1.002 cm2/g, Zeff = 20.62）和Aegirine（密度= 3.55 g/cm3, MAC = 1.107 cm2/g, Zeff = 21.66），表现出卓越的屏蔽能力，特别是在低光子能量下。硅铁石（Ferrosilite）（密度= 3.25 g/cm3, MAC = 0.999 cm2/g, Zeff = 20.72）和超硅铁石（Hypersthene）（密度= 3.50 g/cm3, MAC = 0.699 cm2/g, Zeff = 17.67）等正辉石在特定情况下具有竞争力。该研究强调了密度、原子堆积和阴离子-阳离子半径比（RAC = 0.429−1.143）在确定辐射衰减中的关键作用。Hirshfeld表面分析显示，结构致密性进一步增强了γ射线屏蔽性能。这些发现强调了辉石作为高能环境的高级屏蔽材料的潜力，并在光学和电子领域得到了应用。
