论文摘要
$ j^π= 1^ - $^{96} $ zr的性质以下低于$β$ -decay $q_β$ $^{96} $ y的$^{96} $ y的性质已通过高分辨率$γ$ - 射线光谱型衰减之后的高分辨率$γ$ - 射线光谱型进行了调查。从$β$衰减提取的分支比率可以确定在这两种反应中填充的水平的绝对$ E1 $激发强度。合并的数据代表了低于$q_β$值的波功能的全面方法，在Quasiparticle Phonon模型的理论方法中进行了研究。这项研究阐明了与$^{96} $ y $ _ {gs} $ $β$衰减相关的核结构特性，这是高能反应堆抗中毒光谱的三个最重要的贡献者之一。
The nature of $J^π=1^-$ levels of $^{96}$Zr below the $β$-decay $Q_β$ value of $^{96}$Y has been investigated in high-resolution $γ$-ray spectroscopy following the $β$ decay as well as in a campaign of inelastic photon scattering experiments. Branching ratios extracted from $β$ decay allow the absolute $E1$ excitation strength to be determined for levels populated in both reactions. The combined data represents a comprehensive approach to the wavefunction of $1^-$ levels below the $Q_β$ value, which are investigated in the theoretical approach of the Quasiparticle Phonon Model. This study clarifies the nuclear structure properties associated with the enhanced population of high-lying levels in the $^{96}$Y$_{gs}$ $β$ decay, one of the three most important contributors to the high-energy reactor antineutrino spectrum.
