Stepwise contraction of the nf Rydberg shells in the 3d photoionization of multiply-charged xenon ions
S. Schippers, A. Borovik, T. Buhr +8
Triple photoionization of Xe3+, Xe4+ and Xe5+ ions has been studied in the energy range 670-750 eV, including the 3d ionization threshold. The photon-ion merged-beam technique was…
Formation of very low energy states crossing the ionization threshold of argon atoms in strong mid-infrared fields
Benjamin Wolter, Christoph Lemell, Matthias Baudisch +9
Atomic ionization by intense mid-infrared (mid-IR) pulses produces low electron energy features that the strong-field approximation, which is expected to be valid in the tunneling…
A transportable strontium optical lattice clock
N. Poli, M. Schioppo, S. Vogt +4
We report on a transportable optical clock, based on laser-cooled strontium atoms trapped in an optical lattice. The experimental apparatus is composed of a compact source of ultra…
Imaging Molecular Structure through Femtosecond Photoelectron Diffraction on Aligned and Oriented Gas-Phase Molecules
R. Boll, A. Rouzee, M. Adolph +49
This paper gives an account of our progress towards performing femtosecond time-resolved photoelectron diffraction on gas-phase molecules in a pump-probe setup combining optical la…
Improved limit on a temporal variation of from comparisons of Yb and Cs atomic clocks
N. Huntemann, B. Lipphardt, Chr. Tamm +3
Accurate measurements of different transition frequencies between atomic levels of the electronic and hyperfine structure over time are used to investigate temporal variations of t…
Absolute cross sections for photoionization of Xe ions (1 q 5) at the 3d ionization threshold
S. Schippers, S. Ricz, T. Buhr +26
The photon-ion merged-beams technique has been employed at the new Photon-Ion spectrometer at PETRA III (PIPE) for measuring multiple photoionization of Xe (q=1-5) ions. Tot…
