This image depicts the radium atom’s pear-shaped nucleus of protons and neutrons in the center, surrounded by a cloud of electrons (yellow), and an electron (yellow ball with arrow) that has a ...

Researchers have been able to initiate a controlled movement in the very heart of an atom. They caused the atomic nucleus to interact with one of the electrons in the outermost shells of the atom.

An international research collaboration led by the University of Surrey's Nuclear Physics Group has overturned the long-standing belief that the atomic nucleus of lead-208 (²⁰⁸Pb) is perfectly ...

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 ...

What happens when the smallest building blocks of matter refuse to play by the rules of traditional physics? For decades, atomic nuclei have posed a stubborn puzzle: at low energies, they appear as ...

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 ...
