【摘要】 以中子诱发235U裂变产生的135Xe的累积产额数据为例,利用了所有可利用的实验数据,介绍了裂变产物产额数据的评价方法,包括数据的收集、修正、评价、误差调整和数据处理,特别是协方差数据的评价、半经验模型理论计算数据的应用和相关数据的处理,给出了135Xe热能点产额的推荐值以及0～20 MeV产额-能量关系曲线。更多还原

【Abstract】 Takeing 135Xe produced by neutron induced fission of 235U as an example,the evaluation method for fission yield was introduced using the all experimental data available.The evaluation procedure includes the experimental data collection,correction,evaluation,error assessment and data analysis.The study of the uncertainty covariance,application of semi-empirical theoretical calculation and the yield energy-dependence of 135Xe in the incident energy range 0~20 MeV were emphasized in this work.更多还原
