Experimental signatures of moderately enhanced octupole correlations at high spin in ${}^{136}$Nd are indicated for the first time. The extracted dipole moments of two negative-parity bands are only two times smaller than those of the lanthanide nuclei with $N\approx 90$ which present well-established octupole correlations. Calculations usingthe cranked quasiparticle random phase approximation and a model of quadrupole-octupole rotations with octupole vibrations reveal the structure of the bands and the enhanced octupole correlations at high spin in ${}^{136}$Nd.

136Nd在高自旋下增强的八极相关性的特征

高自旋中八度相关性适度增强的实验信号。 ${}^{136}$首次显示Nd。提取的两个负奇偶校验带的偶极矩仅比镧系元素核的偶极矩小两倍。$ñ\approx 90$呈现出公认的八极相关性。使用曲柄准粒子随机相位逼近和具有八极振动的四极-八极旋转模型进行的计算揭示了在高自旋下带的结构和增强的八极相关性。${}^{136}$Nd。
