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…
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…
Characterization of large area avalanche photodiodes in X-ray and VUV-light detection
L. M. P. Fernandes, F. D. Amaro, A. Antognini +14
The present manuscript summarizes novel studies on the application of large area avalanche photodiodes (LAAPDs) to the detection of X-rays and vacuum ultraviolet (VUV) light. The o…
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…
