14.8 MeV中子诱发232Th裂变产额测量

摘要

本工作采用直接γ能谱法测量了14.8 MeV中子诱发232 Th裂变的62个产物核的累积产额相对值,通过链产额之和200％归一的方法得到了47个质量链的链产额实验数据,数据精度好于10％.%The relative cumulative yields of 62 fission products were determined using γ-spectrum method for 232Th induced by 14.8 MeV neutron.Using chain yields summation 200％ normalization method,47 chain yields were given,and the data precision is better than 10 ％.
