Many atomic nuclei have a magnetic field similar to that of Earth. However, directly at the surface of a heavy nucleus such ...

This view of the atomic nucleus changed when James Chadwick discovered ... high enough energy to "view" this substructure. "In our model, we made improvements to simulate the phenomenon of pairing ...

As an aid to understanding the atomic nucleus, physicists visualize it in terms of simplified models. A surprisingly fruitful approach is to regard it as a cloudy crystal ball ...

The relative charge of a nucleus is the same as its proton (atomic) number. Key fact: isotopes are forms of an element that have the same number of protons but different numbers of neutrons.
