Electron filmed for first time ever

Researchers have recorded snapshots of electron motion at close to the particle's own natural timescale, which is less than a femtosecond (10-15 seconds). The experiment combines ultrashort light pulses with steady laser light to extract an electron from an atom in a controlled way. With control over the precise moment of extraction, the team was able to cleanly image the electron's quantum state, as they describe in the 22 February Physical Review Letters. This technique could help researchers probe electron-atom interactions in more detail and begin using electrons to observe atoms in the poorly-understood state following ionization.
