摘要
This paper describes the mechanisms by which the nonresonant interaction of photons with atoms can lead to direct emission of two electrons from an atom. We discuss three different light-matter interactions: absorption of one (high energy) photon, Compton scattering of one photon (in both cases utilizing synchrotron radiation) and multiphoton processes in strong femtosecond laser fields. From a mainly experimental and phenomenological perspective the interaction mechanisms and their experimental evidences are discussed. (C) 2003 Elsevier Ltd. All rights reserved.
