The final countdown: In a recent experiment a time delay of 20 as between the electrons emitted from different orbitals of neon atoms was measured by means of laser spectroscopy (see picture). The existence of such a delay has important implications for our understanding of electron correlation and for our capability to characterize electronic dynamics on their natural timescale.
