First measurement of the antihydrogen production cross section through the charge-exchange reaction of low-energy antiprotons with orthopositronium
GBAR Collaboration, P. Adrich, I. Belosevic +42
The GBAR experiment has measured the formation rate of antihydrogen from antiproton impact on a positronium cloud for antiproton kinetic energies of 4 and 6 keV. This is the first…
Monitoring antiproton numbers with a CMOS detector in a dense-track environment
C. Regenfus, P. Adrich, I. Belosevic +42
The production of antihydrogen by the GBAR experiment at AD/ELENA requires good knowledge of the number of incident keV antiprotons, which can be problematic. We have used a commer…
A determination of the backscattering probability of low-energy antiprotons
GBAR Collaboration, K. Park, E. Perez +42
It is commonly assumed that antiprotons impinging on a material surface annihilate promptly with the nuclei of the material. However, at kinetic energies of a few keV, this assumpt…
Spectroscopy of the Hyperfine Structure of HD in Rotationally Excited States with 10-ppb Uncertainty
D. Kliukin, V. Barbé, T. Klijn Velderman +5
We report the first measurement of the total hyperfine interval in the manifold of the () rovibrational state of HD using microwave spectroscopy of HD ions in a li…
Determination of a set of fundamental constants from molecular hydrogen ion spectroscopy: a modeling study
J. -Ph Karr, S. Schiller, V. I. Korobov +1
The rovibrational transition frequencies of molecular hydrogen ions (MHI) can be accurately computed using ab initio nonrelativistic quantum electrodynamics. A subset of the fundam…
Extraction of spin-averaged rovibrational transition frequencies in HD for the determination of fundamental constants
Jean-Philippe Karr, Jeroen C. J. Koelemeij
We present a comprehensive analysis of all currently available high-accuracy frequency measurements of rotational and rovibrational transitions in the hydrogen molecular ion HD…
Hydrogen molecular ions for improved determination of fundamental constants
J. -Ph Karr, L Hilico, Jeroen Koelemeij +1
The possible use of high-resolution rovibrational spectroscopy of the hydrogen molecular ions H + 2 and HD + for an independent determination of several fundamental constants is an…
