摘要

本文提供了一个模板,用于评估单能或白中子源实验室(n, xn)测量的中子弹性和非弹性散射截面和γ射线产生截面的实验不确定性。根据对现有数据的调查和许多在该领域具有广泛知识的实验学家和理论家的输入,提出了探测散射中子或由此产生的去激发γ射线的典型不确定性范围。还讨论了通常用于评估所得截面的模型。对数据评估需要哪些实验和不确定度信息提出了建议,并在报告实验(n, xn)截面时应包括这些信息。如果不确定性值和相关性不能从文献中估计出来,建议使用不确定性值和相关性。

Templates of expected measurement uncertainties for (n, xn) cross sections
A template is provided for evaluating experimental uncertainties for neutron elastic and inelastic scattering cross sections and γ -ray production cross sections from (n, xn) measurements at laboratories with monoenergetic or white neutron sources. A typical range of uncertainties is presented for experiments detecting the scattered neutrons or the resulting de-excitation γ rays based on a survey of available data and input from many experimentalists and theorists with extensive knowledge in the field. Models commonly used to evaluate the resulting cross-sections are also discussed. Suggestions are made regarding what experimental and uncertainty information is needed for data evaluations and should be included when reporting experimental (n, xn) cross sections. Uncertainty values and correlations are recommended if these values cannot be estimated for past data from the literature.
