摘要

利用离线伽马射线光谱技术，首次测量了表镉中子诱导 245Cm 裂变中 128、130、132Sb、131、133Te、132、134I、135Xe 和 138Cs 的独立异构体产率（IR）。表镉中子谱的平均能量（<E n >）为 1.9 MeV。通过自旋相关统计模型分析，从红外值推导出了均方根碎片角矩（J RMS）。本研究中裂变产物的红外值和 JRMS 值与 245Cm 热中子诱发裂变的文献数据进行了比较，以研究激发能的作用。此外，还研究了核结构对 J RMS 值的影响。

Independent isomeric yield ratios of fission products in the epi-cadmium neutron-induced fission of 245Cm

Independent isomeric yield ratios (IR) of 128,130,132Sb, 131,133Te, 132,134I, 135Xe and 138Cs in the epi-cadmium neutron-induced fission of 245Cm have been measured for the first time by using an off-line gamma-ray spectrometric technique. The average energy of the epi-cadmium neutron spectrum (<E n >) is 1.9 MeV. From the IR values, root mean square fragment angular momenta (J RMS) were deduced by using the spin dependent statistical model analysis. The IR and JRMS values of the fission products from the present work were compared with the literature data in the thermal neutron-induced fission of 245Cm to examine the role of excitation energy. Effect of nuclear structure on J RMS value was also examined.
