Hydrogen and helium separate at pressures and temperatures found within the gas giant Jupiter’s marbled exterior is pretty familiar territory, but it’s still not clear what happens far below the cloud ...

This demanding experiment is only possible with the help of PSI's proton accelerator facility. There Aldo Antognini's team generates so-called muonic helium-3, in which the two electrons of the helium ...

A research team has achieved a significant breakthrough in determining fundamental properties of atomic nuclei. The team conducted laser spectroscopy experiments on muonic helium-3. Muonic helium-3 is ...

In Wednesday’s issue of Nature, a new paper describes a potentially useful way of measuring the interactions between normal matter and exotic particles, like antiprotons and unstable items like kaons ...

(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 ...

For decades, researchers have toyed with antimatter while searching for new laws of physics. These laws would come in the form of forces or other phenomena that would strongly favor matter over ...

Peter Klavins in the Helium Recovery Facility at the UC Davis Department of Physics and Astronomy. The new facility allows researchers to save on helium, which is limited in supply and increasing in ...

Scientists are able to selectively knockout nucleons and preformed nuclear clusters from atomic nuclei using high-energy proton beams. In an experiment the existence of preformed helium nuclei at the ...

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 ...
