One way to take fast snapshots is to ionize an atom or molecule and then use the released electrons as probes of the cloud out of which they originate. Now Gabriel Stewart at Wayne State University in Michigan and colleagues [<a href=\"https:\/\/physics.aps.org\/articles\/v16\/27#c1\" class=\"\">1<\/a>] and Antoine Camper at the University of Oslo in Norway and colleagues [<a href=\"https:\/\/physics.aps.org\/articles\/v16\/27#c2\" class=\"\">2<\/a>] have improved this \u201cself-probing\u201d technique. The demonstrations could lead to a better understanding of the electron motion that underpins many fundamental processes.<\/p>\n<p>Scientists need to complete three key tasks to measure the evolution of an electron cloud that moves and changes on an ultrafast timescale. The first is to exactly record the beginning of the evolution\u2014analogous to pressing \u201cstart\u201d on a mechanical stopwatch. The second is to track how much time has gone by since the starting event\u2014analogous to precisely measuring the ticking of the stopwatch\u2019s second hand. And the third is to take a quick snapshot of the electron cloud so that it looks frozen in time.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Two groups demonstrate innovative ways to capture the ultrafast motion of electrons in atoms and molecules.
