摘要
描述了通过测量裂变碎片的 γ射线来研究测量中子的方法。2 3 8U薄片的裂变碎片由聚脂膜俘获 ,其γ射线由 Na I(Tl)探测器测量。在不同系统上测量了中子 ,测量结果与用裂变室的测量结果一致。分析和讨论了实验结果。
In this paper the method of measuring neutrons is studied by measuring the γ rays from fission fragments of a U 238 foil, which are captured or collected in polyester foils. γ rays from fission fragments in the polyester foils are measured with a NaI (Tl) detector. Neutrons are measured in different systems. The measuring results are consistent with that from a fission chamber. The experimental results are analyzed and discussed.
