Open AccessAngular dependence of the Wigner time delay upon tunnel ionization of H2
When a very strong light field is applied to a molecule an electron can be ejected by tunneling. In order to quantify the time-resolved dynamics of this ionization process, the concept of the Wigner time delay...

Ultra-fast Dynamics in Quantum Systems Revealed by Particle Motion as Clock
To explore ultra-fast dynamics in quantum systems one needs detection schemes which allow time measurements in the attosecond regime. During the recent decades, the pump & probe two-pulse laser technique has p...

Magnetic fields alter strong-field ionization
When a strong laser pulse induces the ionization of an atom, momentum conservation dictates that the absorbed photons transfer their momentum to the electron and its parent ion. The sharing of the photon momen...

Open AccessPublisher Correction: Imaging the square of the correlated two-electron wave function of a hydrogen molecule
The original version of this Article contained an error in the fifth sentence of the first paragraph of the ‘Application on H2’ section of the Results, which incorrectly read ‘The role of electron correlation is ...

Open AccessImaging the square of the correlated two-electron wave function of a hydrogen molecule
The toolbox for imaging molecules is well-equipped today. Some techniques visualize the geometrical structure, others the electron density or electron orbitals. Molecules are many-body systems for which the co...

Imaging the structure of the trimer systems 4He3 and 3He4He2
Helium shows fascinating quantum phenomena unseen in any other element. In its liquid phase, it is the only known superfluid. The smallest aggregates of helium, the dimer (He2) and the trimer (He3) are, in their ...

Probing the tunnelling site of electrons in strong field enhanced ionization of molecules
Molecules show a much increased multiple ionization rate in a strong laser field as compared with atoms of similar ionization energy. A widely accepted model attributes this to the action of the joint fields o...

Single photon double ionization of \(\mbox{\sffamily\bfseries H}_{\hbox{\sffamily\bfseries\fontsize{10}{12}\selectfont 2}}\) by circularly polarized photons at a photon energy of 160 eV
We report on fully differential cross sections for double ionization of H2 by a single circularly polarized photon of 160 eV energy. For an unequal sharing of the energy between the two electrons and a particular...
