The helion charge radius from laser spectroscopy of muonic helium-3 ions
The CREMA Collaboration, Karsten Schuhmann, Luis M. P. Fernandes +37
Hydrogen-like light muonic ions, in which one negative muon replaces all the electrons, are extremely sensitive probes of nuclear structure, because the large muon mass increases t…
1S-3S cw spectroscopy of hydrogen/deuterium atom
Pauline Yzombard, Simon Thomas, Lucile Julien +2
We study the 1S-3S two-photon transition of hydrogen in a thermal atomic beam, using a homemade cw laser source at 205 nm. The experimental method is described, leading in 2017 to…
High-Resolution Hydrogen Spectroscopy and the Proton Radius Puzzle
Simon Thomas, Hélène Fleurbaey, Sandrine Galtier +3
High resolution spectroscopy of the hydrogen atom takes on particular importance in the new SI, as it allows to accurately determine fundamental constants, such as the Rydberg cons…
New measurement of the transition frequency of hydrogen: contribution to the proton charge radius puzzle
Hélène Fleurbaey, Sandrine Galtier, Simon Thomas +6
We present a new measurement of the two-photon transition frequency of hydrogen, realized with a continuous-wave excitation laser at 205 nm on a room-temperature atomic bea…
The proton radius puzzle
J. J. Krauth, K. Schuhmann, M. Abdou Ahmed +49
High-precision measurements of the proton radius from laser spectroscopy of muonic hydrogen demonstrated up to six standard deviations smaller values than obtained from electron-pr…
Cross-damping effects in 1S-3S spectroscopy of hydrogen and deuterium
Hélène Fleurbaey, François Biraben, Lucile Julien +2
We calculate the cross-damping frequency shift of a laser-induced two-photon transition monitored through decay fluorescence, by adapting the analogy with Raman scattering develope…
