这么大的原子核不可能是稳定的，但在足够长的时间内，在真空附近组装一个原子核以观察真空的衰变是可能的。
A nucleus that large cannot be stable, but it might be possible to assemble one next to a vacuum for long enough to observe the decay of the vacuum.
为了寻找更稳定的方法来储存量子信息，Awschalom已经计算出一个电子的旋转与附近氮原子核旋转的的联系。
In search of a more stable way to store quantum information, Awschalom has now figured out how to link the spin of a electron to the spin of the nearby nitrogen's nucleus.
标准模型认为，原子中原子核的组成部分—质子是稳定不变的，但是许多后标准模型理论却不支持这种观点。
The Standard Model says that protons, which help make up the nuclei of atoms, are stable, but many post-Standard Model theories disagree.
有阴影的格子表示稳定的原子核。
当一个中子轰击一个原子核的时候，这个核可能会俘获这个中子，从而变的极不稳定。
