Towards a test of the weak equivalence principle of gravity using anti-hydrogen at CERN

Publikováno v: Conference on Precision Electromagnetic Measurement
Conference on Precision Electromagnetic Measurement, Jul 2016, Ottawa, Canada. pp.7540781, ⟨10.1109/CPEM.2016.7540781⟩

International audience; The aim of the GBAR (Gravitational Behavior of Antimatter at Rest) experiment is to measure the free fall acceleration of an antihydrogen atom, in the terrestrial gravitational field at CERN and therefore test the Weak Equival

The deuteron is too small, too The radius of the proton has remained a point of debate ever since the spectroscopy of muonic hydrogen indicated a large discrepancy from the previously accepted value. Pohl et al. add an important clue for solving this

Les mesures absolues de fréquences optiques : la révolution des peignes de fréquences

Autor: F. Biraben

Publikováno v: Journal de Physique IV (Proceedings). 12:3-10

Les frequences optiques etant plus grandes que les frequences microonde par quatre a cinq ordres de grandeur, leur mesure par rapport a l'horloge a cesium est tres difficile. Jusqu'a ces dernieres annees. ces mesures ne pouvaient se faire qu'a l'aide

Optical Frequency Measurement of the2S−12DTransitions in Hydrogen and Deuterium: Rydberg Constant and Lamb Shift Determinations

Autor: C. Schwob, L. Jozefowski, B. de Beauvoir, L. Hilico, F. Nez, L. Julien, F. Biraben, O. Acef, J.-J. Zondy, A. Clairon

Publikováno v: Physical Review Letters. 82:4960-4963

We have performed a pure optical frequency measurement of the $2S\ensuremath{-}12D$ two-photon transitions in atomic hydrogen and deuterium. From a complete analysis taking into account this result and all other precise measurements (by ourselves and

Metrological features of the rubidium two-photon standards of the BNM-LPTF and Kastler Brossel Laboratories

Autor: A. Clairon, R. Felder, D. Touahri, O. Acef, Laurent Hilico, F. Biraben

Publikováno v: The European Physical Journal Applied Physics. 4:219-225

We have built three optical frequency standards based on the two-photon transition of rubidium at 778 nm, and analysed their performance over a period of more than three years. We discuss some systematic effects that could lead to the reproducibility

Frequency measurement of the two-photon transition in rubidium

Autor: Ouali Acef, Laurent Hilico, F. Biraben, B. de Beauvoir, André Clairon, D. Touahri, R. Felder, Jean Jacques Zondy, F. Nez

Publikováno v: Optics Communications. 133:471-478

We have measured the frequencies of three diode lasers stabilized on the 5 S 1 2 (F = 3)−5 D 5 2 (F = 5) two-photon transition in rubidium at λ = 778.1 nm, with an uncertainty of 1 kHz, using BNM-LPTF frequency synthesis chain starting from a CO 2

High Resolution Spectroscopy of the Hydrogen Atom: Determination of the1SLamb Shift

Autor: S. Bourzeix, B. de Beauvoir, M. D. Plimmer, D. N. Stacey, F. Nez, F. de Tomasi, Lucile Julien, F. Biraben

Publikováno v: Physical Review Letters. 76:384-387

We have measured the 1{ital S} Lamb shift by comparing the frequencies of the 1{ital S}{sub 1/2}-3{ital S}{sub 1/2} and 2{ital S}{sub 1/2}-6{ital S}{sub 1/2} or 2{ital S}{sub 1/2}-6{ital D}{sub 5/2} two-photon transitions. Our result is 8172.798 (46)
