Combining laser cooling and Zeeman deceleration for precision spectroscopy in supersonic beams
Gloria Clausen, Laura Gabriel, Josef A. Agner +4
Precision spectroscopic measurements in atoms and molecules play an increasingly important role in chemistry and physics, e.g., to characterize structure and dynamics at long times…
Metrology in a two-electron atom: The ionization energy of metastable triplet helium ()
Gloria Clausen, Kai Gamlin, Josef A. Agner +2
Helium (He) is the ideal atom to perform tests of ab-initio calculations in two-electron systems that consider all known effects, including quantum-electrodynamics and nuclear-size…
Imaging-assisted single-photon Doppler-free laser spectroscopy and the ionization energy of metastable triplet helium
Gloria Clausen, Simon Scheidegger, Josef A. Agner +2
Skimmed supersonic beams provide intense, cold, collision-free samples of atoms and molecules are one of the most widely used tools in atomic and molecular laser spectroscopy. High…
Multipole-moment effects in ion-molecule reactions at low temperatures: part I -- Ion-dipole enhancement of the rate coefficients of the He + NH and He + ND reactions at collision energies near K
Valentina Zhelyazkova, Fernanda B. V. Martins, Josef A. Agner +2
The energy dependence of the rates of the reactions between He and ammonia (NY, Y= {H,D}), forming NY, Y and He as well as NY, Y and He, and the corresponding…
Ion-molecule reactions below 1~K: Observation of a strong enhancement of the reaction rate of the ion-dipole reaction He+ CHF
Valentina Zhelyazkova, Fernanda B. V. Martins, Josef A. Agner +2
The reaction between He and CHF forming predominantly CH and CHF has been studied at collision energies between 0 and ~K in a me…
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…
