    For the ionization of gaseous samples, most ion mobility spectrometers employ radioactive ionization sources, e.g., containing 63Ni or 3H. Besides legal restrictions, radioactive materials have the disadvantage of a constant ...
  • Brennecke, Simon; Lein, Manfred (Bristol : Institute of Physics Publishing, 2018)
    Photoelectron momentum distributions from strong-field ionization are calculated by numerical solution of the one-electron time-dependent Schrödinger equation for a model atom including effects beyond the electric dipole ...
  • Dreissigacker, Ingo; Lein, Manfred (College Park, MD : American Physical Society, 2014)
    Motivated by recent experiments on circular dichroism in the photoelectron momentum distributions from strong-field ionization of chiral molecules [C. Lux, Angew. Chem. Int. Ed. 51, 5001 (2012)1433-785110.1002/anie.201109035; ...
  • Chacon, Alexis; Lein, Manfred; Ruiz, Camilo (College Park, MD : American Physical Society, 2013)
    We extend the ideas of wave-packet interferometry to implement the algorithm of spectral phase interferometry for direct electric-field reconstruction (SPIDER) for characterizing the amplitude and phase of electron wave ...
  • Bunert, Erik; Heptner, Andre; Reinecke, T.; Kirk, Ansgar T.; Zimmermann, Stefan (College Park, MA : American Institute of Physics (AIP), 2017)
    Ion mobility spectrometers (IMS) are devices for fast and very sensitive trace gas analysis. The measuring principle is based on an initial ionization process of the target analyte. Most IMS employ radioactive electron ...
  • Brée, C.; Hofmann, M.; Demircan, A.; Morgner, Uwe; Kosareva, O.; Savel'Ev, A.; Husakou, A.; Ivanov, M.; Babushkin, I. (American Physical Society, 2017)
    The ionization rate of an atom in a strong optical field can be resonantly enhanced by the presence of long-living atomic levels (so-called Freeman resonances). This process is most prominent in the multiphoton ionization ...
  • Ni, Hongcheng; Brennecke, Simon; Gao, Xiang.; He, Pei-Lun; Donsa, Stefan; Březinová, Iva; He, Feng; Wu, Jian; Lein, Manfred; Tong, Xiao-Min; Burgdörfer, Joachim (College Park, MD : American Physical Society, 2020)
    Interaction of a strong laser pulse with matter transfers not only energy but also linear momentum of the photons. Recent experimental advances have made it possible to detect the small amount of linear momentum delivered ...
  • Jürgens, P.; Jupé, M.; Gyamfi, M.; Ristau, Detlev (Bellingham, WA : S P I E - International Society for Optical Engineering, 2016)
    The modeling of the laser-induced damage processes can be divided into thermal and electronic processes. Especially, electronic damage seems to be well understood. In corresponding models, the damage threshold is linked ...
