When nuclei catch up with electrons Researchers Put Electron in New Controlled State

Researchers Put Electron in New Controlled State

A team of European physicists managed to prove a 50 year old hypothesis: that electrons could be both freed and constrained to a nucleus.

Henneberger wondered if there was any way to free an electron from the atom while still keeping it near the nucleus. The researchers also showcased how effectively lasers could be used to study this phenomenon. Moreover, we discovered that electrons placed in such states can amplify light. Electrons can at times be torn away from a nucleus via an electric laser, overcoming the force keeping it to its nucleus.
