| 摘 要： | 在大气颗粒物离子束分析中,质子诱发γ射线分析（PIGE）作为质子诱发X荧光发射（PIXE）的补充方法,通常用于分析轻元素。为得到外束PIGE定量分析气溶胶样品中F和Na元素的最佳实验条件,本工作在北京师范大学串列加速器上测定了质子能量在1.8～2.9 MeV范围内,核反应19F(p,p’γ)19F（Eγ=110 keV和197 keV）和 23Na(p,p’γ)23Na(Eγ=440 keV)的γ射线激发函数。

| Abstract: | Proton induced γ-ray emission (PIGE) is commonly used as a complementary technique of proton induced X-ray emission (PIXE) for the analysis of light elements in aerosol samples. In order to get the best operating conditions of PIGE for F and Na determination in aerosol samples relative to thin reference standards in an external beam setup, the γ-ray yields of the reaction 19F(p,p’γ) 19F（Eγ=110 keV and 197 keV） and 23Na(p,p’γ) 23Na (Eγ=440 keV) were measured for incident protons in the energy range of 1.8-2.9 MeV at the external beam facility of the 1.7 MV tandem accelerator in Beijing Normal University. |
