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 ...
For the first time, researchers from the PRISMA + Cluster of Excellence have determined the charge radius of helium-3 and thus also the exact difference to the radius of helium-4. This precision ...
For the current experiment, the scientists struck a target of alpha particles (helium-4 nuclei) with a beam of argon-34. (The number after an isotope indicates its total number of protons and neutrons ...
One of nature's simplest elements is giving scientists a big headache after new research shows that protons and neutrons in helium atoms are not behaving as theory suggests they should. The mismatch ...
New helium measurements in distant galaxies could provide solutions to a long-standing cosmology problem, potentially explaining why the universe isn't empty. Reading time 4 minutes When theoretical ...

Scientists found a universal rule hiding in cosmic rays — every type of particle fades at the exact same threshold
Helium nuclei, carbon nuclei, oxygen nuclei: three very different particles, all screaming through the Milky Way at nearly ...
A new measurement of the strong nuclear force, which binds protons and neutrons together, confirms previous hints of an uncomfortable truth: We still don’t have a solid theoretical grasp of even the ...
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 ...
