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…
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…
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…
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…
