这篇文章是第五个在一系列的基本物理的光产额非比例性在制冷剂。在这里，我们比较和对比的非比例性注册的伽马射线和高能电子。如过去已经注意到的，这两种类型的数据具有不同的曲线形状（对于光产额对电子或伽马能量的绘图）。在这里，我们展示了如何实验伽马非比例曲线可以计算从电子响应占高能量电子的分布所产生的伽马光子通过光电相互作用。同样，我们测量和建模的伽马诱导的分辨率作为能量的函数，并比较这些数据从我们的模型预测。该模型的实用性进行了探索，使用与SrI2（Eu），GYGAG（Ce）和CsI（Na）的闪烁体获得的数据。
This paper is the fifth in a series of articles on the basic physics of light yield nonproportionality in scintillators. Here, we compare and contrast the nonproportionality as registered by gamma rays and high-energy electrons. As has been noted in the past, these two types of data have different curve shapes (for plots of the light yield against electron or gamma energy). Herein, we show how the experimental gamma nonproportionality curve can be calculated from the electron response by accounting for the distribution of high energy electrons created by the gamma photon via the photoelectric interaction. Similarly, we measure and model the gamma-induced resolution as a function of energy and compare this data to predictions from our model. The utility of the model is explored using data acquired with the scintillators SrI2(Eu), GYGAG(Ce) and CsI(Na).
