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…
Lifetimes and g-factors of the HFS states in H-like and Li-like bismuth
Volker Hannen, Jonas Vollbrecht, Zoran Andelkovic +23
The LIBELLE experiment performed at the experimental storage ring (ESR) at the GSI Helmholtz Center for Heavy Ion Research in Darmstadt, Germany, has successfully determined the gr…
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…
Measurement of the charged pion mass using a low-density target of light atoms
M Trassinelli, D. F. Anagnostopoulos, G Borchert +10
We present a new evaluation of the negatively charged pion mass based on the simultaneous spec-troscopy of pionic nitrogen and muonic oxygen transitions using a gaseous target comp…
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…
Measurement of the charged pion mass using X-ray spectroscopy of exotic atoms
M Trassinelli, D. F. Anagnostopoulos, G. Borchert +10
The transitions in pionic nitrogen and muonic oxygen were measured simultaneously by using a gaseous nitrogen-oxygen mixture at 1.4\,bar. Due to the precise knowledge of th…
