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...

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 ...

Resonant Auger decay driving intermolecular Coulombic decay in molecular dimers
Intermolecular Coulombic decay transfers excess energy to neighbouring molecules, which then lose a low-energy (and, hence, genotoxic) electron; here the process is experimentally confirmed to be site-selectiv...

Understanding the role of phase in chemical bond breaking with coincidence angular streaking
Electron motion in chemical bonds occurs on an attosecond timescale. This ultrafast motion can be driven by strong laser fields. Ultrashort asymmetric laser pulses are known to direct electrons to a certain di...

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...
