The “lead” of a pencil is actually made of a substance called graphite which is made of carbon atoms. The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and ...

The word magic is not often used in the context of science. But in the early 1930s, scientists discovered that some atomic nuclei—the center part of atoms, which make up all matter—were more stable ...

For the first time, quarks and gluons were used to describe properties of atomic nuclei, which until now had been explained by the existence of protons and neutrons. The temporary pair of correlated ...

In the middle of the last century, physicists found that protons can resonate, much like a ringing bell. Advances over the last three decades have led to 3D pictures of the proton and significant ...

Physicists have discovered a surprising new “Island of Inversion” in a place no one expected: among nuclei where the number of protons equals the number of neutrons. For decades, these strange regions ...

A new measurement of the strong nuclear force, which binds protons and neutrons together, confirms previous hints of an uncomfortable truth: We still don’t have a solid theoretical grasp of even the ...

A researcher stands behind a metal pipe covered with electrical cords and gauges. A researcher works on a device at the Facility for Rare Isotope Beams. This part of the facility provides low-energy ...
