摘要

摘要:利用离线伽玛射线谱技术，测定了241 Pu在镉镉中子诱导裂变过程中130,132 Sb, 131,133 Te, 134,136 I, 135 Xe和138 Cs的独立同分异构体产率(IR)。中子平均能量(<epi-镉反应堆中子谱的E n >)为1.9 MeV。利用自旋相关统计模型分析，从红外光谱值推导出碎片角动量的均方根。研究了核结构对jrms值的影响。本文将外镉中子诱导241钚裂变的实验数据与热中子诱导241钚裂变的实验数据进行了比较，探讨了激发能对碎片角动量的影响。

Independent isomeric yield ratios of fission products in the epi-cadmium neutron induced fission of ²⁴¹Pu

Abstract Independent isomeric yield ratios (IR) of 130,132 Sb, 131,133 Te, 134,136 I, 135 Xe and 138 Cs have been measured in the epi-cadmium neutron induced fission of 241 Pu by using an off-line gamma-ray spectrometric technique. The average neutron energy (< E n >) of the epi-cadmium reactor neutron spectrum is 1.9 MeV. From the IR values, root mean square fragment angular momenta ( J RMS ) were deduced by using spin dependent statistical model analysis. Effect of nuclear structure on J RMS values was examined. The present data in the epi-cadmium neutron induced fission of 241 Pu were compared with the similar data in the thermal neutron induced fission of 241 Pu to examine the role of excitation energy on fragment angular momentum.
