摘要
一、引言对于高浓铀燃料、金属铍反射层,主要作为中子活化分析用的微型反应堆而言,对有关辐照座内的能谱和谱参数必须有所了解,中子温度是重要的谱参数,它基本上反映了反应堆热谱的特征。
In the paper the neutron temperature and epithermal index in the irradiationsites of CIAE MNSR and PARR-II (Pakistan MNSR) are determined with ^(176)Lu-^(64)Dy and ^(115)In-^(55)Mn by double foils method and Cadmium ratio method. Theresults obtained by both methods agree with each other. The agreements of bothmethods are 1.2% for neutron temperature and 9.1% for epithermal index.
