At the heart of every atomic nucleus, the strong interaction quietly dictates the structure of matter, yet for decades one of ...

Neutron stars are what remain after giant stars collapse, leaving behind a body so dense that its core crushes protons and neutrons into a tightly packed soup. These objects cool very slowly over ...

Neutron stars are ultra-dense star remnants made up primarily of nucleons (i.e., protons and neutrons). Over the course of ...

For decades, nuclear physicists believed that "Islands of Inversion"—regions where the normal rules of nuclear structure ...

Nuclear puzzle: In the nucleus, neutrons can be stable, but free neutrons decay after a short period. Exactly how short is in dispute because experiments on neutrons stored in bottles and neutrons in ...

The double-slit experiment is the most famous and probably the most important experiment in quantum physics: individual particles are shot at a wall with two openings, behind which a detector measures ...

While all atomic nuclei except hydrogen are composed of protons and neutrons, physicists have been searching for a particle consisting of two, three or four neutrons for over half a century.

Protons in neutron-rich nuclei have a higher average energy than previously thought, according to a new analysis of electron scattering data that was first collected in 2004. The research appears to ...
