“…This structure automatically ruled out "shake-off" (Fittinghoff et al 1992) or "collective tunnelling" (Eichmann et al 2000) as dominant NS double ionisation mechanisms terminating a ten years discussion. At the same time, the peaks were found to be compatible with the "antenna" (Kuchiev 1987) or the "recollision" mechanism (Corkum 1993) as was first shown within classical considerations Moshammer et al 2000;Weber et al 2000).…”

Recoil-ion and electron momentum spectroscopy is a rapidly developing technique that allows one to measure the vector momenta of several ions and electrons resulting from atomic or molecular fragmentation. In a unique combination, large solid angles close to π Microccopes -the "bubble chambers of atomic physics" -mark the decisive step forward to investigate many-particle quantum-dynamics occurring when atomic and molecular systems or even surfaces and solids are exposed to time-dependent external electromagnetic fields.The present review concentrates on just these latest technical developments and on at least four new classes of fragmentation experiments that have emerged within about the last five years. First, multi-dimensional images in momentum space brought unprecedented information on the dynamics of single-photon induced fragmentation of fixed-in-space molecules and on their structure. Second, a break-through in the investigation of highintensity short-pulse laser induced fragmentation of atoms and molecules has been achieved by using Reaction Microccopes. Third, for electron and ion-impact, the investigation of twoelectron reactions has matured to a state such that first fully differential cross sections (FDCS) are reported. Forth, comprehensive sets of FDCS for single ionisation of atoms by ion-impact, the most basic atomic fragmentation reaction, brought new insight, a couple of surprises and unexpected challenges to theory at keV to GeV collision energies. In addition, a brief summary on the kinematics is provided at the beginning. Finally, the rich future potential of the method is shortly envisaged.2

“…Elliptical (close-tocircular) polarization is thought to prevent recollision in many situations and is therefore ideally suited for answering this question. Shake-up excitation of a two-electron system in intense laser fields has been measured [4], and there has been speculation about collective tunnelling [5] or inelastic tunnelling [6]. To date, quantum calculations simulating double ionization by elliptically polarized fields exceed the capability of current computers [7].…”

“…Whereas the comparably narrow distribution without any ATI structure (above threshold ionization) for singly charged ions is well described by tunneling ionization (at a Keldish parameter [15] of γ = 0.35), a pronounced double peak structure along the polarization direction was found for double and triple ionization [16]. This structure automatically rules out "shake-off" [17] or "collective tunneling" [18] as dominant NS double ionization mechanism as will be illustrated below. On the other hand, the peaks were found to be compatible with the "antenna -" [20] or the "recollision mechanism" [21] as was first shown within classical considerations [16,19].…”

Using "Reaction Microscopes" that enable to detect the vector momenta of several electrons and ions after fragmentation of atoms or molecules, pathways for multiple electron ejection in femtosecond PW/cm 2 Laser fields have been explored in unprecedented detail. Classical boundaries for "recollision", which is identified to be the dominant multiple ionization mechanism, are analyzed. The electron-electron correlation in Ne double ionization is explored, Coulomb repulsion between the emerging electrons is demonstrated for Ar double ionization, the importance of excitation -field-ionization mechanisms is elucidated and sub-threshold multiple ionization processes are discussed. Future possibilities as the realization of an "attosecond streak-camera" at free electron lasers are envisaged.
