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…
Charge radii of Cl isotopes from x-ray spectroscopy of muonic atoms
K. A. Beyer, T. E. Cocolios, C. Costache +25
Nuclear charge radii are vital for nuclear and atomic physics, the determination of fundamental constants, and searches for new physics. Muonic atoms, where a single negative muon…
Muonic atom spectroscopy with microgram target material
A. Adamczak, A. Antognini, N. Berger +26
Muonic atom spectroscopy -- the measurement of the x rays emitted during the formation process of a muonic atom -- has a long standing history in probing the shape and size of nucl…
Modern approach to muonic x-ray spectroscopy demonstrated through the measurement of stable Cl radii
K. A. Beyer, T. E. Cocolios, C. Costache +25
Recent advances in muonic x-ray experiments have reinvigorated efforts in measurements of absolute nuclear charge radii. Here, a modern approach is presented, and demonstrated thro…
Planar LAAPDs: Temperature Dependence, Performance, and Application in Low Energy X-ray Spectroscopy
L. Ludhova, F. D. Amaro, A. Antognini +25
An experiment measuring the 2S Lamb shift in muonic hydrogen mup is being performed at the Paul Scherrer Institute, Switzerland. It requires small and compact detectors for 1.9 keV…
The next generation of laser spectroscopy experiments using light muonic atoms
S. Schmidt, M. Willig, J. Haack +41
Precision spectroscopy of light muonic atoms provides unique information about the atomic and nuclear structure of these systems and thus represents a way to access fundamental int…
