Nuclear weapons haven’t been tested in the United States since 1992. Find out why, and what could happen if the hiatus ends.

Target preparation techniques are fundamental to nuclear physics experiments as they provide the essential interface where high-energy reactions occur. Researchers employ a range of fabrication ...

An international research team led by the Paul Scherrer Institute PSI has measured the radius of the nucleus of muonic helium-3 with unprecedented precision. The results are an important stress test ...

In an article published in 2002 in the journal Physics Letters B, my Ph.D. student Maurizio Piai (now Professor of Physics at Swansea University, Swansea, UK) and I proposed an experiment with reactor ...

To address critical research challenges in heavy-ion collisions at Fermi-energy regimes—specifically targeting the nuclear equation of state (nEoS), Femtoscopic interferometry of light nuclei, and ...

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 ...
