Precision spectroscopy of helium and related atomic systems continues to serve as a cornerstone of experimental and theoretical quantum physics, offering stringent tests of quantum electrodynamics and ...

Hunting for (alpha,n) reactions: The experimental set-up in the ISAC-II hall at TRIUMF. (Courtesy: M Williams) New measurements by physicists from the University of Surrey in the UK have shed fresh ...

(Nanowerk News) In experiments at the Paul Scherrer Institute PSI, an international research collaboration has measured the radius of the atomic nucleus of helium five times more precisely than ever ...

Pionic helium In this experiment, a pion – shown here with one orange and one blue particle representing its quark and anti-quark – replaces one of the two electrons in the helium atom. This new ...

The interest in exotic atoms arises from the fact that they often facilitate the most basic experimental strategy used in physics: changing a single parameter or component in an otherwise complex ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. If you start with a mass of hydrogen gas and bring it together under ...
