摘要
本文报道了用多道分析仪及７６．２ｍｍ×７６．２ｍｍＮａＩ探测器测量０～９ＭｅＶ辐射场复杂γ谱的实验与解析方法，提出了解析方程组并推导了变量系数的数学表达式。用该方法对Ｃｄ俘获γ能量分１９个区作了实验检验，结果与文献报道的数据基本一致。
This paper deseribes the method for measuring and analyzing 0～9 MeV γ ray energy spectrum for radiation field by multichannel analyzer and φ76 2mm×76.2mm NaI detector.The equation resolving spectrum and mathematical expressions with variable coefficient have been presented.In order to check the methd,thermal neutron capture γ spectrum,which was divided into nineteen energy intervals,was measured and resolved,and was compared with the data from the literature,Results show that determined spectrum is in good agreement with that of literature.
