摘　　要：使用大液体闪烁探测器,相对于金的俘获截面测量了铕(Eu)六个能量点的中子俘获截面值;用光学模型和统计理论计算了^(151)Eu和^(153)Eu在0.1—2.0Mev能区的中子俘获截面;对实验测量和理论计算结果进行了分析和讨论.The measurements of fast neutron capture cross sections of Eu relative to Au at six neutron energies were carried out by using a large liquid scintillator detector. zhe neutron capture cross sections of ^(151)Eu and ^(153)Eu were calculated in the range of 0.1 to 2.0 MeV using the optical model and statistical theory.Present results are compared with other experiment and discussed.
