Multiphoton Double Ionization of Helium at 394nm - a Fully Differential Experiment
K. Henrichs, S. Eckart, A. Hartung +11
We report on a kinematically complete experiment on strong field double ionization of helium using laser pulses with a wavelength of 394\,nm and intensities of $3.5-5.7\times10^{14…
Direct Experimental Access to the Nonadiabatic Initial Momentum Offset upon Tunnel Ionization
S. Eckart, K. Fehre, N. Eicke +11
We report on the non-adiabatic offset of the initial electron momentum distribution in the plane of polarization upon single ionization of argon by strong field tunneling and show…
Timing Recollision in Nonsequential Double Ionization by Intense Elliptically Polarized Laser Pulses
H. Kang, K. Henrichs, M. Kunitski +10
We examine correlated electron and doubly charged ion momentum spectra from strong field double ionization of Neon employing intense elliptically polarized laser pulses. An ellipti…
Absolute ion detection efficiencies of microchannel plates and funnel microchannel plates for multi-coincidence detection
K. Fehre, D. Trojanowskaja, J. Gatzke +11
Modern momentum imaging techniques allow for the investigation of complex molecules in the gas phase by detection of several fragment ions in coincidence. For these studies, it is…
Ultrafast Preparation and Detection of Ring Currents in Single Atoms
Sebastian Eckart, Maksim Kunitski, Martin Richter +16
Quantum particles can penetrate potential barriers by tunneling (1). If that barrier is rotating, the tunneling process is modified (2,3). This is typical for electrons in atoms, m…
