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 …

The past decade has seen extraordinary theoretical progress in the field of fully
kinematically resolved atomic electron-impact ionisation, and its closely related field 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 investigated the full three-dimensional momentum correlation between the
electrons emitted from strong field double ionization of neon when the recollision energy of …

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 …

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 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 …

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 …

Much progress in the theory of positron scattering on atoms has been made in the ten years
since the review of Surko et al (2005 J. Phys. B: At. Mol. Opt. Phys. 38 R57). We review this …
