的中子能量依赖的角分布测量individualrays从3.2 eV波共振，这表明增强宇称违反由于混合之间的波振幅。射线从波共振的过渡进行了鉴定，相对于中子动量的角分布进行了评价作为一个函数的中子能量为7132 keV射线，这对应于过渡到1807 keV的激发态的。角分布被认为是起源于与波振幅之间的干涉，并将提供一个基础，定量理解的基本宇称破坏的增强机制在复合核。
A neutron-energy dependent angular distribution was measured for individualrays from the 3.2 eV-wave resonance of, that shows enhanced parity violation owing to a mixing between- and-wave amplitudes. The-ray transitions from the-wave resonance were identified, and the angular distribution with respect to the neutron momentum was evaluated as a function of the neutron energy for 7132 keVrays, which correspond to a transition to the 1807 keV excited state of. The angular distribution is considered to originate from the interference between- and-wave amplitudes, and will provide a basis for a quantitative understanding of the enhancement mechanism of the fundamental parity violation in compound nuclei.
