摘要
针对钨酸铅晶体(PbWO4)在137Cs源作用下所得的脉冲幅度谱,并结合蒙特卡罗模拟,提出了一种获得光产额较低的闪烁晶体光产额的新的拟合方法。此方法亦适用于其它晶体。
A new fitting method together with the Monte Carlo simulation is developed to process the full pulse-height spectrum of a 137 Cs source in PbWO_4 crystals to get the precise light yield of the crystal in photoelectrons per MeV. This method is also useful for other kinds of crystal measurements.
