0.70～2.48 MeV质子在F和Mg上160°背散射截面测量

Non-Rutherford 160° Backscattering Cross Sections of 0.70-2.48 MeV Protons on Fluorine and Magnesium

摘要: 应用北京师范大学2×1.7 MV串列静电加速器提供的质子束，采用相对测量方法测量了0.70～2.48 MeV 宽能区质子在轻核F和Mg上160°（实验室坐标系）背散射截面。测量得到F、Mg各自对应能区的质子共振背散射截面数据，为含F、Mg轻元素的新型薄膜材料的高灵敏分析提供了实验数据。

Abstract: Differential elastic 160° backscattering cross sections of 0.70-2.48 MeV protons on fluorine and magnesium were measured by relative measuring method. The analysis proton beams were provided by 2×1.7 MV accelerator at Beijing Normal University. The resonance backscattering cross sections of F and Mg were presented in graphical forms, which should be useful for the sensitive analysis of new thin-film materials with F and Mg.
