Helium is the simplest element in the periodic table with more than one particle in its nucleus, yet state of the art theory and experiments on it don't add up. Skip to main content Open menu ...

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.

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 ...
