Astrophysicists are turning the universe’s dying stars into laboratories for one of physics’ most elusive ideas, the axion.

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 ...

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.

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 ...
