Observed energy levels of (162)Er from the normal state J = 0 to the excited rotational state J = 18 correspond to values of the moment of inertia and rotational frequency that indicate that a pronounced change in structure occurs at about J = 14. It is shown that the observed values agree well with the values calculated on the assumption that there is resonance between a more stable prolate structure with a core of two spherons and a less stable superprolate structure with a core of three spherons in line.
从正常态(J = 0)到激发转动态(J = 18)观测到的（(162)）铒的能级对应的转动惯量和转动频率值表明，在(J)约为(14)时结构发生了显著变化。结果表明，观测值与基于以下假设计算得到的值吻合得很好：在一个由两个球状体组成核心的更稳定的长椭球形结构与一个由三个球状体排成一线组成核心的较不稳定的超长椭球形结构之间存在共振。
