Electron Emission Delay Is Clue To Dynamics

Laser experiments reveal 20 attosecond difference between an electron’s ejection time from the 2p orbital versus the 2s orbital
Department: Science & Technology
Keywords: attosecond, photoemission

It takes about 20 attoseconds longer for a neon atom to emit an electron from its 2p orbital than from its 2s orbital after absorbing a photon, reports a group led by Martin Schultze, Vladislav S. Yakovlev, and Ferenc Krausz of Ludwig Maximilian University of Munich and Max Planck Institute of Quantum Optics, both in Germany (Science 2010, 328, 1658). The researchers observed the photoemission . . .
