Delayed time zero in photoemission: New record in time measurement accuracy

Thursday, June 24, 2010 - 13:00 in Physics & Chemistry

German physicists have discovered a time delay when using light pulses to emit electrons from atoms. Until now, it has been assumed that the electrons start moving out of the atom immediately after the impact of the photons. This delay is the shortest time interval measured to date. Science journal reports on their findings in the tomorrow's issue.
