    • Laser-induced electron diffraction of the ultrafast umbrella motion in ammonia 

      Belsa, B.; Amini, K.; Liu, X.; Sánchez, A.; Steinle, T.; Steinmetzer, J.; Le, A. T.; Moshammer, R.; Pfeifer, T.; Ullrich, J.; Moszynski, R.; Lin, C. D.; Grafe, S.; Biegert, Jens (AIP, 2021-01-13)
      Article
      Open Access
      Visualizing molecular transformations in real-time requires a structural retrieval method with Ångström spatial and femtosecond temporal atomic resolution. Imaging of hydrogen-containing molecules additionally requires an ...
    • Molecular structure retrieval directly from laboratory-frame photoelectron spectra in laser-induced electron diffraction 

      Sánchez, A.; Amini, K.; Wang, S.-J.; Steinle, T.; Belsa, B.; Danek, J.; Le, A. T.; Liu, X.; Moshammer, R.; Pfeifer, T.; Richter, M.; Ullrich, J.; Gräfe, S.; Lin, C. D.; Biegert, Jens (Nature Research, 2021-03-09)
      Article
      Open Access
      Ubiquitous to most molecular scattering methods is the challenge to retrieve bond distance and angle from the scattering signals since this requires convergence of pattern matching algorithms or fitting methods. This ...
    • Role of high ponderomotive energy in laser-induced nonsequential double ionization 

      Shaaran, T.; Camus, N.; Dura, J.; Fechner, L.; Thai, A.; Britz, A.; Baudisch, M.; Steinle, T.; Senftleben, A.; Schröter, C. D.; Ullrich, J.; Pfeifer, T.; Keitel, C. H.; Biegert, Jens; Hatsagortsyan, K. Z.; Moshammer, R. (APS, 2019-02-19)
      Article
      Open Access
      The laser-induced nonsequential double ionization (NSDI) of rare gas atoms in the near and mid-IR laser fields is studied experimentally and theoretically. We investigate electron-electron correlation at high recollision ...
    • Ultrafast electron diffraction imaging of bond breaking in di-ionized acetylene 

      Wolter, B.; Pullen, M. G.; Le, A.-T.; Baudisch, M.; Doblhoff-Dier, K.; Senftleben, A.; Hemmer, M.; Schröter, C. D.; Ullrich, J.; Pfeifer, T.; Moshammer, R.; Gräfe, S.; Vendrell, O.; Lin, C. D.; Biegert, Jens (Science, 2016-10-16)
      Article
      Open Access
      Visualizing chemical reactions as they occur requires atomic spatial and femtosecond temporal resolution. Here, we report imaging of the molecular structure of acetylene (C2H2) 9 femtoseconds after ionization. Using ...
