４．４ＤＣＯ比的效率修正李广生在高自旋态谱学中，γ－γ符合测量是常用的实验技术，它是确定γ跃迁的级联关系和建立能级纲图的基础。为了节省加速器的用机时间并提高符合计数的统计精度，现在大多采用由多个Ｇｅ探测器组成的探测系统，在进行γ－γ符合测量的同时，可... 4.4 Efficiency Correction of DCO Ratio In the high spin spectroscopy, γ-γ coincidence measurement is a commonly used experimental technique. It is the basis for determining the cascade relationship of γ transitions and establishing the energy level diagram. In order to save the time spent on the accelerator and improve the statistical accuracy of the counting, most of the detection systems made up of a plurality of Ge detectors are now used, and when the gamma-gamma coincidence measurement is carried out, ...
