美国弗吉尼亚共同体大学物理学教授施夫·汉纳和他的同行在实验室中将金属铝制成蒸气,在这个过程中形成了一些由多个铝原子组成的极其微小的球,其中由13个铝原子组成的小球最稳定。他们从铝蒸气中过滤出这些AL13“超级原子”,让它们与呈链形的碘分子发生化学反应。结果发现AL13 Shiv Hannah, a professor of physics at the University of Virginia School of the United States, and his colleagues made metal aluminum vapors in the laboratory. In the process, they formed tiny balls of aluminum atoms, 13 of them. The ball composed of aluminum atoms is the most stable. They filter out these AL13 “super-atoms” from the aluminum vapor, causing them to chemically react with the chain-shaped iodine molecules. Results found AL13
