There Aldo Antognini's team generates so-called muonic helium-3, in which the two electrons of the helium atom are replaced by an elementary particle called a muon. This allows the nuclear radius ...

Scientists can't figure out why forces within the helium atom's nucleus continue to defy theory after decades of experiments. (Image credit: Getty) ...

Physicists have created the first-ever atomic vortex beam — a swirling tornado of atoms and molecules with mysterious properties that have yet to be understood.

In 1975, a paper was published in the prestigious journal Physical Review Letters that was co-authored by a cat. This wasn’t ...

Only about one helium-3 atom exists for every million helium-4 atoms, Horton said. The team measured about 10 million helium-3 atoms per gram of olivine crystals.

Two helium-3s then fuse to form a stable helium atom, leaving two hydrogen nuclei available to start the process all over again. Contributed / Bob King. These circumstances, ...

Instead of water, they used a nanoscopic droplet of liquid helium cooled to -273°C as the solvent – and instead of a grain of salt, they used an atom of sodium.. The researchers embedded a ...
