JPGeγ谱仪峰总比不变性的实验研究

Experiment Research on Invariability of Peak-to-Total Ratio in γ-ray Spectrometry

测定了点源、面源和盘状源在距HPGe探测器表面不同距离上的峰总比，研究了探测器的峰总比随样品形状和测量几何条件的变化规律，验证了同一探测器不同测量条件下峰总比基本不变的特性，给出了所使用HPGeγ谱仪的峰总比曲线。

： The source, such as point, plane and disc were measured in several sourcedetector distances for the research on invariability of the peak-to-total ratio, and the curve of peak-to-total ratio was presented.
