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…
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…
Theory of the n=2 levels in muonic helium-3 ions
Beatrice Franke, Julian J. Krauth, Aldo Antognini +3
The present knowledge of Lamb shift, fine-, and hyperfine structure of the 2S and 2P states in muonic helium-3 ions is reviewed in anticipation of the results of a first measuremen…
Laser Spectroscopy of Muonic Atoms and Ions
Randolf Pohl, François Nez, Luis M. P. Fernandes +44
Laser spectroscopy of the Lamb shift (2S-2P energy difference) in light muonic atoms or ions, in which one negative muon is bound to a nucleus, has been performed. The measur…
Theory of the Lamb shift and Fine Structure in muonic ions and the muonic Isotope Shift
Marc Diepold, Beatrice Franke, Julian J. Krauth +3
We provide an up to date summary of the theory contributions to the 2S-2P Lamb shift and the fine structure of the 2P state in the muonic helium ion . This summ…
Experiments towards resolving the proton charge radius puzzle
A. Antognini, K. Schuhmann, F. D. Amaro +34
We review the status of the proton charge radius puzzle. Emphasis is given to the various experiments initiated to resolve the conflict between the muonic hydrogen results and the…
Multipass laser cavity for efficient transverse illumination of an elongated volume
Jan Vogelsang, Marc Diepold, Aldo Antognini +11
A multipass laser cavity is presented which can be used to illuminate an elongated volume from a transverse direction. The illuminated volume can also have a very large transverse…
Quantum interference effects in laser spectroscopy of muonic hydrogen, deuterium, and helium-3
Pedro Amaro, Beatrice Franke, Julian J. Krauth +9
Quantum interference between energetically close states is theoretically investigated, with the state structure being observed via laser spectroscopy. In this work, we focus on hyp…
Improved X-ray detection and particle identification with avalanche photodiodes
Marc Diepold, Luis M. P. Fernandes, Jorge Machado +36
Avalanche photodiodes are commonly used as detectors for low energy x-rays. In this work we report on a fitting technique used to account for different detector responses resulting…
Lifetime and population of the 2S state in muonic protium and deuterium
Marc Diepold, Fernando D. Amaro, Aldo Antognini +32
Radiative deexcitation (RD) of the metastable 2S state of muonic protium and deuterium atoms has been observed. In muonic protium, we improve the precision on lifetime and populati…
