Journal ArticleDOI

The GBAR antimatter gravity experiment

TL;DR: The GBAR project at CERN as mentioned in this paper measured the free fall acceleration of ultracold neutral anti hydrogen atoms in the terrestrial gravitational field, which consists preparing anti hydrogen ions (one antiproton and two positrons) and sympathetically cooling them with Be (+) ions.
Journal ArticleDOI

Measuring the α-particle charge radius with muonic helium-4 ions

TL;DR: In this paper, the root-mean-square charge radius of a muonic helium-4 ion was determined using laser spectroscopy, which is in excellent agreement with the value from electron scattering, but a factor of 4.8 more precise.
Journal ArticleDOI

Deuteron charge radius and Rydberg constant from spectroscopy data in atomic deuterium

TL;DR: In this paper, a pedagogical description of the method to extract the charge radii and Rydberg constant from laser spectroscopy in regular hydrogen (H) and deuterium (D) atoms, that is part of the CODATA least-squares adjustment (LSA) of the fundamental physical constants.
Journal ArticleDOI

Progress in Spectroscopy of the 1S–3S Transition in Hydrogen

TL;DR: In this paper, the Doppler-free spectroscopy of the 1S-3S transition in hydrogen has been investigated and a new continuous ultra-violet source has been developed and delivered a power level of 15 mW.
Journal ArticleDOI

Precise determination of the ratio h/m u: a way to link microscopic mass to the new kilogram

TL;DR: In this paper, the authors present the state-of-the-art on experiments that provide the most precise value of the Planck constant for the measurement of the atomic recoil due to the photon momentum.
