An international research team led by the Paul Scherrer Institute PSI has measured the radius of the nucleus of muonic 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 ...

Helium is the simplest element in the periodic ... major cosmic mystery 'Beauty' particle discovered at world's largest atom smasher could unlock new physics 'Primordial' helium from the birth ...

Researchers at University of Cambridge and University of Newcastle recently introduced a new method to measure helium atom diffraction with microscopic spatial resolution. This method, outlined in ...

When U-238 decays into Th-234 (upper left), it liberates an alpha particle, which is a helium nucleus. The particle quickly picks up two electrons, creating a new atom of helium. Source ...

In very intense radiation fields, however, the atom may simultaneously absorb multiple photons, and these can give rise to multiple emission pathways. Jiang and colleagues have done a theoretical ...

“And what scientific treasures they turned out to be!” 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 ...

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. By sending a straight beam of ...
