摘要

进一步提出被测元素瞬发γ射线特征峰的面积与其含量的关系式。经实验证明对各常见元素的仪器分析回归值与化学分析值的均方根偏差皆小于０．５ｗｔ％。在铁矿石的分析实验中发现了慢化体的作用，它可明显地提高分析灵敏度。该套中子俘获瞬发γ谱仪对Ｈ瞬发γ峰崐（２．２２３ＭｅＶ）的ＦＷＨＭ为３ｋｅＶ。

Abstract

MENG Bonian （China Institute of Atomic Energy

Beijing 102413） Abstract The relationship between content of the measured elements and area of typical peaks of prompt Y - rays is presented. The root- mean square errors on both the regression

value of instrumentation analysis and chemical analysis for some common elements are lower than 0.5wt%. Function of the slowing body was found and analysis sensitivity was enhanced obviously in the iron ore analysis. The FWHM of the spectrometer for the H prompt Y - ray peak （2.223MeV） is 3keV.
