Abstract

In order to improve the quality of neutron data for U in CENDL, considering the impact of new measurements, a brand-new evaluation of the complete set of neutron induced U reaction data up to 20 MeV has been performed. Important reactions, such as (n,tot), (n,γ), (n,f), (n,2n) and (n,3n) reaction cross sections and average number of fission neutrons have been evaluated based on experimental data analysis. Also, using existing optical model potential parameters, new theoretical calculations based on Hauser-Feshbach and pre-equilibrium model have been carried out. Resonance parameters and prompt fission neutron spectrum from ENDF/B-VIII.0 have been adopted. Guided by integral benchmark, (n,inl), (n,γ) and (n,f) reaction cross sections have undergone multiple adjustments, leading to a noticeable improvement in data quality, as indicated by final benchmark results.

20 MeV 以下 238U 中子反应的评估和计算
为了提高 CENDL 中铀中子数据的质量,考虑到新测量结果的影响,对 20 MeV 以下的整套中子诱导铀反应数据进行了全新的评估。根据实验数据分析,对重要的反应,如(n,tot)、(n,γ)、(n,f)、(n,2n)和(n,3n)反应截面和裂变中子的平均数量进行了评估。同时,利用现有的光学模型势参数,基于豪瑟-费斯巴赫和前平衡模型进行了新的理论计算。共振参数和ENDF/B-VIII.0的瞬裂变中子谱被采用。在积分基准的指导下,(n,inl)、(n,γ)和(n,f)反应截面进行了多次调整,从而使数据质量得到明显改善,最终基准结果表明了这一点。
