A rather complete understanding is emerging of the process of full fragmentation of the
helium atom following absorption of a single photon. In this review the major experimental …

The substantial progress that has occurred during the 1990s in the field of electron-atom-
collision theory is discussed. We show how a solution of a small-model three-body problem …

We have investigated the full three-dimensional momentum correlation between the
electrons emitted from strong field double ionization of neon when the recollision energy of …

All properties of molecules—from binding and excitation energies to their geometry—are
determined by the highly correlated initial-state wavefunction of the electrons and nuclei …

We have measured fully differential cross sections for photo double ionization of helium 450
eV above the threshold using the COLTRIMS technique. We have found an extremely …

We have measured absolute triple differential cross sections for photo-double ionization of
helium at 20 eV excess. The measurement covers the full ranges of energy sharing and …

A time-dependent close-coupling method is used to calculate, for the first time, fully
differential cross sections for the complete fragmentation of helium by two photons …

We perform a systematic study of photoionization with excitation and double photoionization
of H−, He, and Li+ using the convergent close-coupling formalism. The present calculations …

We determine, both experimentally and theoretically, the fully resolved fivefold differential
cross section (5DCS) of double ionization of helium by 5.6 keV electron impact. Symmetric …

The dynamics of He double ionization by 2 keV electron impact is studied experimentally for
a momentum transfer of 0.6 au at excess energies of 10 and 40 eV. Complete sets of fivefold …
