The independent isomeric yield ratios (IR) of Sb, Te, I, Xe and Cs have been measured in the epi-cadmium neutron induced fission of U by using an off-line gamma-ray spectrometric technique. The average neutron energy of the epi-cadmium reactor neutron spectrum is 1.9 MeV. The root mean square fragment angular momenta (J) were deduced from the IR values by using spin dependent statistical model analysis. The IR and J values of considered fission products in the epi-cadmium neutron induced fission of U were compared with the literature data in the thermal neutron induced fission of U to examine the influence of excitation energy on nuclear structure effect.
利用离线γ射线能谱技术，测量了超镉中子诱发U裂变中Sb、Te、I、Xe和Cs的独立同分异构体产额比（IR）。超镉反应堆中子能谱的平均中子能量为1.9 MeV。通过自旋相关统计模型分析，从IR值推导出均方根碎片角动量（J）。将超镉中子诱发U裂变中所考虑裂变产物的IR和J值与热中子诱发U裂变的文献数据进行比较，以研究激发能对核结构效应的影响。
