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 …

Recoil-ion and electron momentum spectroscopy is a rapidly develo** technique that
allows one to measure the vector momenta of several ions and electrons resulting from …

Over the last four decades an experimental method has been developed for looking at
electron orbitals in momentum space. The method, called electron momentum spectroscopy …

The wave nature of particles is rarely observed, in part because of their very short de Broglie
wavelengths in most situations. However, even with wavelengths close to the size of their …

We report on the observation of doubly charged helium ions produced by a nonlinear
interaction between a helium atom and photons with a photon energy of 42 eV which are …

The attosecond pump probe, in close analogy to the standard femtosecond probing
technique, has been proposed and theoretically demonstrated with its application to explore …

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 present a demonstration of two-photon double ionization of neon using an intense
extreme ultraviolet (XUV) attosecond pulse train (APT) in a photon energy regime where …

The study of the emission of two electrons from an atom by absorption of a single energetic
photon has become of much current interest because it provides the most detailed …

Single, double, and triple ionization of C 1+ ions by single photons is investigated in the
energy range of 286–326 eV, ie, in the range from the lowest-energy K-vacancy resonances …
