Physicists just discovered a brand-new particle that appears to be an exotic cousin to the protons and neutrons that make up ...

The new particle, named Xi-cc-plus, carries two heavy charm quarks and is about four times heavier than an ordinary proton.

Physicists have found a new “island of inversion” in the nucleus of molybdenum-84, a perfectly balanced atom with equal numbers of protons and neutrons. The discovery upends a decades-old assumption ...

If you hit an atom’s nucleus hard enough, it will fall apart. But exactly how it falls apart tells us something about the internal structure of the nucleus and perhaps about the interior of neutron ...

A research team is using astrophysical explosions to understand the mysterious forces at work in some of the smallest ...

Physicists have discovered a surprising new “Island of Inversion” in a place no one expected: among nuclei where the number ...

Fast-moving protons are much more likely to pair up with fast-moving neutrons than with other protons in the nuclei of atoms, according to a recent experiment. The research confirms a previous ...

OAK RIDGE, Tenn. — Examining the smallest parts of the universe often takes the biggest kinds of equipment. At Oak Ridge National Laboratory, a unique piece of equipment the size of a building is ...

Scientists have harnessed the power of artificial intelligence to unlock secrets hidden within the ...

The structure of a neutron or a proton is modified when the particle is bound in an atomic nucleus. Experimental data suggest an explanation for this phenomenon that could have broad implications for ...

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 ...
