In a feat of modern-day alchemy, atom tinkerers have fooled hydrogen atoms into accepting a helium atom as one of their own. The camouflaged atom behaves chemically like hydrogen, but has four ...

The interest in exotic atoms arises from the fact that they often facilitate the most basic experimental strategy used in physics: changing a single parameter or component in an otherwise complex ...

Laser physicists have captured an atomic-level event – an electron being ejected from a helium atom after being struck by a photon – with an accuracy of a trillionth of a billionth of a second ...

The artificial atom was stable for several nanoseconds, or a few billionths of a second. A short time indeed, but over 1,000 times longer than typical interactions between atomic nuclei and pions ...

Muonic helium-3 is a special form of helium in which the atom s two electrons are replaced by a single, much heavier muon. Skip to main content. Your source for the latest research news.
