论文摘要
我们研究20NE的簇结构，并表明可用的实验数据可以通过具有D（3H）对称性的双层型结构来很好地描述。发生这种对称性的有力证据来自观察到所有九种预期振动模式（3个单一变性和3个双重变性）和六种（单一简并）双振动模式。 20NE似乎是复杂性程序中简单性的另一个例子，其中简单的光谱特征是由复杂的多体系统出现的。
We study the cluster structure of 20Ne and show that the available experimental data can be well described by a bi-pyramidal structure with 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.
