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…

Ultrafast electron localization in a correlated metal

Jose R. L. Mardegan, Serhane Zerdane, Giulia Mancini +27

Ultrafast electron delocalization induced by a fs laser pulse is a well-known process and is the initial step for important applications such as fragmentation of molecules or laser…

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…
