裂变产物核的截面在核工程领域有重要的应用。特别是在时间长,中子场很强的情况下,这些裂变产物核(包含寿命较短的裂变产物核)在中子作用下,再度产生和消失从而使产物核数发生变化,研究这一动态变化,就需知道这些裂变产物核的中子反应截面的大小。目前,国际上也缺少很多裂变产物核素的截面数据。本工作在收集现有的国际上的中子截面评价数据的基础上,同时采用理论计算的方法补充了420个产物核中子数据,建立了1 121个裂变产物核(A=66~172,Z=22~
Fission product nuclear cross-section in nuclear engineering has an important application. Especially in the case of a long time, the neutron field is strong, these fission product nuclei (including short life fission product nuclei) in the neutron, again produce and disappear so that the product of the nucleus changes, to study this Dynamic changes, we need to know the size of these fission product nuclear neutron reaction cross-section. At present, there is a lack of cross-sectional data on many fission product nuclides in the world. Based on the collection of the existing international evaluation data of neutron cross sections, this work supplemented 420 nuclear neutron data with theoretical calculations and established 1 121 fission product nuclei (A = 66 ~ 172, Z = 22 ~
