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…
Thin-disk laser multi-pass amplifier
K. Schuhmann, M. A. Ahmed, T. Graf +8
In the context of the Lamb shift measurement in muonic helium we developed a thin-disk laser composed of a Q-switched oscillator and a multi-pass amplifier delivering pulses of 150…
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…
Broadband Electrically Detected Magnetic Resonance Using Adiabatic Pulses
F. M. Hrubesch, G. Braunbeck, A. Voss +2
We present a broadband microwave setup for electrically detected magnetic resonance (EDMR) based on microwave antennae with the ability to apply arbitrarily shaped pulses for the e…
