Âé¶¹ÒùÔºicists test quantum theory with atomic nuclei from a nuclear reaction

Many atomic nuclei have a magnetic field similar to that of Earth. However, directly at the surface of a heavy nucleus such as lead or bismuth, it is trillions of times stronger than Earth's field and more comparable to that ...
