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 γrays,their peak’s area not only records the matters of opticalelectronic effect but also the Compton scattering matters with higher energyγrays.So that,theγrays intensity conducted by the peak’s area can’t gain.Using the anti-matrix method,the better results of anlyze on theγSpectrometry may be getten.Abstract: When the sample contains many kinds of energies γrays,their peak’s area not only records the matters of opticalelectronic effect but also the Compton scattering matters with higher energyγrays.So that,theγrays intensity conducted by the peak’s area can’t gain.Using the anti-matrix method,the better results of anlyze on theγSpectrometry may be getten.
