背景：低位八极集体激发在描述核素图不同区域的原子核结构中发挥着重要作用。在几个原子核中已知结合了正宇称态和负宇称态的基态交替宇称旋转带。实验数据表明，随着角动量的增加，八极变形变得稳定。
Background: Low-lying octupole collective excitations play an important role in describing the structure of nuclei in different regions of the nuclide chart. Ground state alternating-parity rotational bands combining both positive- and negative-parity states are known in several nuclei. The experimental data indicate that octupole deformation becomes stable with increase of the angular momentum.
