Extraction of XUV+IR ionization amplitudes from the circular dichroic phase
Anatoli Kheifets
A strong helicity dependence of reconstruction of attosecond bursts by beating of two-photon transitions (RABBITT) with circularly polarized XUV and IR pulses was reported by Han e…
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…
Effect of electron correlations on attosecond photoionization delays in the vicinity of the Cooper minima of argon
D. Hammerland, P. Zhang, A. Bray +10
Attosecond photoionization delays have mostly been interpreted within the single-particle approximation of multi-electron systems. The strong electron correlation between the photo…
Separating Dipole and Quadrupole Contributions to Single-Photon Double Ionization
S. Grundmann, F. Trinter, A. W. Bray +12
We report on a kinematically complete measurement of double ionization of helium by a single 1100 eV circularly polarized photon. By exploiting dipole selection rules in the two-el…
Sub-Cycle Interference upon Tunnel-Ionization by Counterrotating Two-Color Fields
S. Eckart, M. Kunitski, I. Ivanov +12
We report on three-dimensional (3D) electron momentum distributions from single ionization of helium by a laser pulse consisting of two counterrotating circularly polarized fields…
Attosecond Streaking in the Water Window: A New Regime of Attosecond Pulse Characterization
Seth L. Cousin, Nicola Di Palo, Bárbara Buades +6
We report on the first streaking measurement of water-window attosecond pulses generated via high harmonic generation, driven by sub-2-cycle, CEP-stable, 1850 nm laser pulses. Both…
