Analyze of Sample γ Spectrometry with Mathmatics Simulating

摘要: 当样品含有多种能量的γ射线时，某一峰下的面积，不仅记录了该能量的光电效应事件，而且还包括了更高能量γ射线的Compton 散射事件。这样，就不能由峰下面积确定相应的γ射线强度，采用逆矩阵法对γ能谱进行分析可得到较好非结果。When the sample contains many kinds of energies γrays,their peak’s area not only records the matters of opticalelectronic effect but also the Compton scattering matters with higher energyγrays.So that,theγrays intensity conducted by the peak’s area can’t gain.Using the anti-matrix method,the better results of anlyze on theγSpectrometry may be getten.
