A scientific team led by Facility for Rare Isotope Beams, or FRIB, has identified the origin of a mysterious excess of ...

In a single experiment, physicists have measured the "excess" emission of high-energy gamma rays from more than a dozen heavy ...

The original version of this story appeared in Quanta Magazine. A new measurement of the strong nuclear force, which binds protons and neutrons together, confirms previous hints of an uncomfortable ...

Nearly every object we interact with in our lives has a mass, but where does this mass come from? Modern physics says matter acquires its mass from interaction with a physical vacuum—it is not an ...

Nuclear physicists used a little magic in their latest experiment conducted at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility, and the result has revealed surprising ...

Some atomic nuclei are thin-skinned — they’re surrounded by a slim shell of neutrons. Physicists now know how thick that neutron skin is for one particular type of nucleus. The skin of lead-208 — a ...

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 before. With the ...

Researchers of the GSI Helmholtzzentrum für Schwerionenforschung and the Technical University in Darmstadt, together with an international team, succeeded in producing and detecting the long-sought ...
