1.引言金属团簇中壳结构的故事在核物理学中有一个较早的相似之处。许多年前，人们注意到含有8、20、50、82或126个质子或中子的原子核具有很长的寿命。对于20世纪40年代的核物理学家来说，解释这些所谓的魔术数字是一个挑战。由于物理学家倾向于认为大多数物体都是完美的圆形，所以他们假设原子核是球对称的也就不足为奇了。在这种假设下，他们只需解一个径向薛定谔方程：d1，2
1. Introduction The story of shell structure in metal clusters has an earlier parallel in nuclear physics. Many years ago, it was noticed that atomic nuclei containing 8, 20, 50, 82, or 126protons or neutrons have very longlifetimes. It was a challenge for the nuclear physicists in the 1940s to explain these so-called magic numbers. Since physicists tend to see most objects as perfectly round, it should come as no surprise that they assumed atomic nuclei are spherically symmetric. Under this assumption they had to solve only a radial Schrddinger equation: d1 2
