Hyperfine splitting is a familiar phenomenon in atomic physics in which magnetic interactions between the nucleus and the electrons split the electronic energy levels into sublevels. Eberhard Widmann ...

An antimatter experiment at CERN reveals that the hyperfine splitting of antihydrogen is the same as that of hydrogen to four parts in 10,000. The research was done by physicists working on the ...

These days, everybody learns in grade school that an atom looks a bit like a little solar system, with a positively charged nucleus orbited by negatively charged electrons. Hydrogen is the simplest ...

NEWPORT NEWS, VA – While it’s commonplace for many scientists to collaborate on nuclear physics experiments at the U.S. Department of Energy’s Thomas Jefferson National Accelerator Facility, it’s ...

Swansea University scientists working at CERN have again made a landmark finding, taking them one step closer to answering the question of why matter exists and illuminating the mysteries of the Big ...
