Different atoms and ions possess characteristic energy levels. Like a fingerprint, they are unique for each species. Among ...

Technical University of Braunschweig, and the University of Delaware achieved new insight into the inner structure of the ...

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 ...

Physicists have created the heaviest clumps of antimatter particles ever seen. Known as antihyperhydrogen-4, this strange stuff could help us solve some of the most puzzling physics mysteries.

For the first time, quarks and gluons were used to describe properties of atomic nuclei, which until now had been explained by the existence of protons and neutrons. The temporary pair of correlated ...

An artistic representation of antihyperhydrogen-4 — an antimatter hypernucleus made of an antiproton, two antineutrons, and an antilambda particle — created in a collision of two gold nuclei (left).
