用瞬发中子发射鉴定Fission产品产率评价中的杂质
Identifying Inconsistencies in Fission Product Yield Evaluations with Prompt Neutron Emission
摘要：
我们提出了裂变产物产额评价的自洽性分析。异常产量确定使用一系列简单的保守性检查和比较常见的参数化的电荷分布。利用平均电荷守恒，直接从独立裂变产物产额导出了作为产物质量$\barν_T(A)$函数的总瞬发中子多重性。这种方法是检查对蒙特卡罗模拟的Hauser-Feshbach统计衰变框架中的裂变碎片的去激发。导出的$\barν_T(A)$与实验数据进行比较，当可用时，并用于比较各种评价的瞬发中子多重性$\barν$。研究了每次评价的$\barν$差异，并确定了可能的来源。我们还确定了裂变反应，是不一致的即时中子数据，并提出可能的解决方案，以纠正所观察到的不一致。
英文摘要：
We present a self-consistency analysis of fission product yield evaluations. Anomalous yields are determined using a series of simple conservation checks and comparing charge distributions with common parameterizations. The total prompt neutron multiplicity as a function of product mass $\barν_T(A)$ is derived directly from the independent fission product yields using average charge conservation. This method is checked against Monte Carlo simulations of the de-excitation of the fission fragments in a Hauser-Feshbach statistical decay framework. The derived $\barν_T(A)$ is compared with experimental data, when available, and used to compare the prompt neutron multiplicity $\barν$ for the various evaluations. Differences in $\barν$ for each evaluation are investigated and possible sources are identified. We also identify fission reactions that are inconsistent with prompt neutron data and propose possible solutions to remedy the observed inconsistencies.
