Observation of quantum capture in an ion-molecule reaction
Katharina Höveler, Johannes Deiglmayr, Josef A. Agner +3
In 1954, Vogt and Wannier (Phys. Rev. 95, 1190) predicted that the capture rate of a polarizable neutral atom or molecule by an ion should increase by a factor of two compared to t…
Characterization of the electronic ground state of Mg by PFI-ZEKE photoelectron spectroscopy
Matthieu Génévriez, Maxime Holdener, Carla Kreis +1
The ground electronic state of the Mg ion has been studied by pulsed-field-ionization zero-kinetic-energy (PFI-ZEKE) photoelectron spectroscopy. Rotat…
SI-traceable frequency dissemination at 1572.06 nm in a stabilized fiber network with ring topology
Dominik Husmann, Laurent-Guy Bernier, Mathieu Bertrand +18
Frequency dissemination in phase-stabilized optical fiber networks for metrological frequency comparisons and precision measurements are promising candidates to overcome the limita…
Precision Measurements in Few-Electron Molecules: The Ionization Energy of Metastable He and the First Rotational Interval of He
Luca Semeria, Paul Jansen, Gian-Marco Camenisch +3
Molecular helium represents a benchmark system for testing calculations on few-electron molecules. We report on the determination of the adiabatic ionization e…
Precision measurement of the ionization energy and quantum defects of 39K I
Michael Peper, Felix Helmrich, Jonas Butscher +4
We present absolute-frequency measurements in ultracold 39K samples of the transitions from the ground state to np Rydberg states. A global nonlinear regression of the np1/2 and np…
Benchmarking theory with an improved measurement of the ionization and dissociation energies of H
Nicolas Hölsch, Maximilian Beyer, Edcel J. Salumbides +4
The dissociation energy of H represents a benchmark quantity to test the accuracy of first-principles calculations. We present a new measurement of the energy interval between…
