Billard game in an atom: Physicists trace the double ionization of argon atoms on attosecond time scales
(Phys.org) -- When an intense laser pulse interacts with an atom it generates agitation on the micro scale. A rather likely outcome of this interaction is single ionization, where one electron is ejected from ...
