Zeptosecond Birth Time Delay in Molecular Photoionization
Sven Grundmann, Daniel Trabert, Kilian Fehre +11
Photoionization is one of the fundamental light-matter interaction processes in which the absorption of a photon launches the escape of an electron. The time scale of the process p…
Chiral photoelectron angular distributions from ionization of achiral atomic and molecular species
Andreas Pier, Kilian Fehre, Sven Grundmann +12
We show that the combination of two achiral components - atomic or molecular target plus a circularly polarized photon - can yield chirally structured photoelectron angular distrib…
Sideband Modulation by Sub-Cycle Interference
S. Eckart, D. Trabert, K. Fehre +9
We experimentally and theoretically show that the electron energy spectra strongly depend on the relative helicity in highly intense, circularly polarized two-color laser fields wh…
Observation of Photoion Backward Emission in Photoionization of He and N2
Sven Grundmann, Max Kircher, Isabel Vela-Perez +14
We experimentally investigate the effects of the linear photon momentum on the momentum distributions of photoions and photoelectrons generated in one-photon ionization in an energ…
Revealing the Two-Electron Cusp in the Ground States of He and H2 via Quasifree Double Photoionization
S. Grundmann, V. Serov, F. Trinter +15
We report on kinematically complete measurements and ab initio non-perturbative calculations of double ionization of He and H2 by a single 800 eV circularly polarized photon. We co…
