But accelerators could potentially produce nuclear fusion, which fuses atomic nuclei together.

而加速器可能产生核聚变，将原子核融合在一起。

Soon, however, the protons won't be alone, lead ions — whole atomic nuclei — will be smashed up.

然而，随即这些质子便不再孤单，因为铅离子——它的整个原子核——将会被撞毁。

Nuclear fusion - the melding of atomic nuclei that happens inside stars - is a long-sought goal on Earth.

核聚变是发生在恒星内部的原子核融合，是地球上长期追求的目标。

that's one way to think about it, and there's also another way, and this is the way that your book presents it. If you, in fact, have two of the same atom right next to each other, let's say you have a crystal, or let's say you're talking about a metal, what you can do is just look at the distance between the two nuclei, and split that in 1/2, and take the atomic radius that way.

这只是一种定义的思路，另外还有其它方法，也就是你们课本上的方法，如果你，事实上，有两个相同的原子彼此靠在一起，比如说你有一个晶体，或者说你讨论的是一个金属，你所要做的就是,看看这两个原子核之间的距离，然后将距离除以二，就得到了这个原子的半径。

Instead of speeding atomic nuclei up, it slows them down, and turns the energy released into electricity.

Rabi was interested in the properties of atomic nuclei, not clocks, and he never pursued the idea.
