摘　　要：基于Geant4软件包开发了mossbSim模拟软件,模拟了不同振动速度范围、γ放射源与样品及样品与探测器之间不同距离、不同探测器厚度的穆斯堡尔谱.通过对不同实验参量的模拟及对模拟代码、数据分析代码的研究,学生在加深对穆斯堡尔实验理解的同时,了解Geant4模拟软件包的应用及ROOT数据分析软件.The mossbSim simulation software was developed based on the Geant4 package.It could simulate Mossbauer spectra with different vibration speed range,different distance betweenγ-source and sample,different distance between the sample and the detector,and the different thickness of detector.Studying the spectra simulated with different experimental parameters,the simulation code and the data analysis code,students could understand more detail of the M ssbauer experiment,and get a preliminary knowledge of the application of the Geant4 simulation software package and the ROOT data analysis software.
