用0.8-16 MeV的漏中子谱测量对铋的核数据进行了验证。测量实验是在中国原子能科学研究院D-T中子发生器上建立的整体基准装置上进行的。用飞行时间技术在60°和120°测量角下记录了样品泄漏的中子。为了了解评价库中数据文件的准确性对中子输运模拟的影响，采用MCNP-4C程序，结合最新的评价库进行了计算。从中子能谱形状和C/E值等方面与实验结果进行了比较。结果表明，不同数据库的理论模拟在一定能量范围内高估或低估了测量值，数据文件中的次级中子能量分布和角分布对此进行了解释。
A benchmark experiment is carried out with slab sample to validate nuclear data of bismuth by measurement of leakage neutron spectra from 0.8–16 MeV. The measured experiments are performed at China Institute of Atomic Energy with the integral benchmark facility established on the D–T neutron generator. The neutrons leaking from the sample are recorded at the measuring angle of 60° and 120° by time-of-flight technique. To make understanding of the impact of accuracy of data files in evaluated library on the neutron transport simulation, the calculation is carried out by MCNP-4C code with a series of latest available evaluated libraries. The calculated spectra are analyzed by comparing with experimental ones in neutron spectrum shape and C/E values. The result indicates that the theoretical simulation with different data libraries overestimated or underestimated the measured ones in some energy ranges, and the secondary neutron energy distribution and angular distribution in data files have been present to explain it.
