摘要
在天然铀重水零功率堆上，同时在栅格和参考热中子场内照射１组直径和材料与元件芯块相同的探测片。采用相对测量方法，使用γ谱仪系统测定初始转换比，测量结果在５％误差范围内与理论值一致。
Two foils are irradiated in lattice of heavy water zero power reactor and reference thermal neutron field, respectively, and the initial conversion ratio r 0 is determined by relative method. Using the γ spectroscopy system, the net counts under the γ ray peaks of 278 keV from 239 Np and 293 keV from 143 Ce are measured. The measured and theoretic r 0 values are in agreement within the error of 5 %.
