标题： Cluster structure of 20Ne: Evidence for D(3h) symmetry

摘要： 我们研究了20Ne的簇结构，并表明现有的实验数据可以通过具有D(3h)对称性的双金字塔结构很好地描述。 这种对称性出现的有力证据来自于观察到所有九种预期的振动模式（3种单重简并和3种双重简并）以及六种（单重简并）双振动模式。 20Ne似乎是复杂性简单性计划中的另一个例子，在这个计划中，简单的光谱特征来源于复杂的多体系统。 显示英文摘要

摘要： 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.
