Journal ArticleDOI
Double-slit photoelectron interference in strong-field ionization of the neon dimer.
Maksim Kunitski,Nicolas Eicke,Pia Huber,Jonas Köhler,S. Zeller,J. Voigtsberger,Nikolai Schlott,K. Henrichs,H. Sann,Florian Trinter,Lothar Ph. H. Schmidt,Anton Kalinin,Markus Schöffler,Till Jahnke,Manfred Lein,Reinhard Dörner +15 more
TL;DR: The authors show the double-slit interference effect in the strong-field ionization of neon dimers by employing COLTRIMS method to record the momentum distribution of the photoelectrons in the molecular frame.
Journal ArticleDOI
Ultrafast energy transfer between water molecules
Till Jahnke,H. Sann,T. Havermeier,K. Kreidi,C. Stuck,M. Meckel,Markus Schöffler,N. Neumann,R. Wallauer,S. Voss,Achim Czasch,Ottmar Jagutzki,A. Malakzadeh,F. Afaneh,Th. Weber,Horst Schmidt-Böcking,Reinhard Dörner +16 more
TL;DR: In this paper, the authors reported the direct observation of an ultrafast transfer of energy across the hydrogen bridge in (H2O)2 (a so-called water dimer) leading to an ejection of a low-energy electron from the molecular neighbour of the initially excited molecule.
Journal ArticleDOI
Direct Determination of Absolute Molecular Stereochemistry in Gas Phase by Coulomb Explosion Imaging
M. Pitzer,Maksim Kunitski,Allan S. Johnson,Allan S. Johnson,Till Jahnke,H. Sann,Felix Sturm,Lothar Ph. H. Schmidt,Horst Schmidt-Böcking,Reinhard Dörner,Jürgen Stohner,Julia Kiedrowski,Michael Reggelin,Sebastian Marquardt,Alexander Schießer,Robert Berger,Markus Schöffler +16 more
TL;DR: A mass spectrometry approach is demonstrated that directly images the absolute configuration of individual molecules in the gas phase by cold target recoil ion momentum spectroscopy after laser ionization–induced Coulomb explosion.
Journal ArticleDOI
Multiorbital tunneling ionization of the CO molecule.
Jian Wu,Jian Wu,L. Ph. H. Schmidt,Maksim Kunitski,M. Meckel,S. Voss,H. Sann,H. K. Kim,Till Jahnke,Achim Czasch,Reinhard Dörner +10 more
TL;DR: The results confirm that the shape of the ionizing orbitals determine the strong laser field tunneling ionization in the CO molecule, whereas the linear Stark effect plays a minor role.
Journal ArticleDOI
Nonsequential Double Ionization by Counterrotating Circularly Polarized Two-Color Laser Fields.
Sebastian Eckart,Martin Richter,Maksim Kunitski,Alexander Hartung,Jonas Rist,K. Henrichs,Nikolai Schlott,H. Kang,H. Kang,T. Bauer,H. Sann,L. Ph. H. Schmidt,Markus Schöffler,Till Jahnke,Reinhard Dörner +14 more
TL;DR: It is concluded that double ionization is driven by a beam of nearly monoenergetic recolliding electrons, which can be controlled in intensity and energy by the field parameters.
