We study the cluster structure of ²⁰Ne and show that the available experimental data can be well described by a bi-pyramidal structure with ${\mathcal{D}}_{3h}$ symmetry. Strong evidence for the occurrence of this symmetry comes from the observation of all nine expected vibrational modes (3 singly degenerate and 3 doubly degenerate) and of six (singly degenerate) double vibrational modes. ²⁰Ne appears to be another example of the simplicity in complexity program, in which simple spectroscopic features arise out of a complex many-body system.

²⁰ Ne的团簇结构：证据${\mathcal{d}}_{3H}$ 对称

我们研究了²⁰ Ne的团簇结构，并表明可用的双锥体结构可以很好地描述可用的实验数据。${\mathcal{d}}_{3H}$对称。关于这种对称性发生的有力证据来自对所有九种预期振动模式（3种分别退化和3种双重退化）和六种（单独退化）双重振动模式的观察。²⁰ Ne似乎是复杂性程序简化的另一个示例，其中简单的光谱特征来自复杂的多体系统。
