Protons and neutrons–known collectively as nucleons–are both the building blocks of matter, but one of these particles has received a bit more attention in certain types of nuclear physics experiments ...

A neutron star is so dense that one sugar cube of its material would weigh around 1 trillion kilograms.

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 ...

AT SOME point in our lives, most of us learn that atoms are comprised of three types of particle: neutrons, protons and electrons. Each has distinct properties. The electron and proton have opposite ...

Mirror magic: The "cores" of the exotic nuclei oxygen-22 and silicon-22 both resemble that of oxygen-16, with eight protons and eight neutrons. The neutron-rich oxygen isotope contains an additional ...

In the world of nuclear physics, protons often take the spotlight. But now, for the first time, the neutron has stepped into it. A recent experiment using the U.S. Department of Energy's Jefferson Lab ...

A high-precision experiment found no evidence that neutrons can transform into mirror versions and disappear into a parallel ...

Physicists have found the strongest sign yet of a fabled four of a kind. For six decades, researchers have hunted for clusters of four neutrons called tetraneutrons. But evidence for their existence ...

Through mass measurements of silicon-22 combined with theoretical calculations, researchers have revealed that silicon-22 possesses a double-magic structure similar to that of oxygen-22, while also ...
