| 摘 要： | 利用Geant4对含有锰元素的混合材料进行热中子活化模拟,并进行γ射线的探测。符合测量技术利用核素衰变的级联γ射线,对56Mn的特征γ射线进行选取。模拟采用~(56_Mn的846 keV特征射线作为门信号,对与846 keV相级联的特征γ射线进行选择,获取~(56)Mn符合γ谱,根据符合γ能谱验证Geat4软件能模拟~(56)Mn的级联衰变。

Simulation of Coincidence Picking Out Full-Energy-Peaks With MC |
| |
| Abstract: | Using Geant4,a Monte Carlo simulation software,simulates that thermal neutron irradiates the material containing Manganese element.At the same time,the neutron activation analysis spectrometer of the material can be detected by NaI(Tl).Coincidence rneastrement takes the γ cascade of certain element as gate signals to pick out full-energy γ-ray peaks.This experiment uses the full-energy-peak of 846 keV as gate signals to pick out full-energy γ-ray peaks for Manganese element.According to the selected γ-ray spectrum,Geant4 can simulate the γ cascade of Manganese element. |
