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…
Absolute measurement of the relativistic magnetic dipole transition in He-like sulfur
Jorge Felizardo Dias Cunha Machado, Nancy Paul, Gabrielle Soum-Sidikov +5
We have made the first absolute, reference-free measurement of the 1s2s 3 S1 1s 2 1 S0 relativistic magnetic dipole transition in He-like sulfur. The highly-charged S…
Diffusion of muonic hydrogen in hydrogen gas and the measurement of the 1 hyperfine splitting of muonic hydrogen
J. Nuber, A. Adamczak, M. Abdou Ahmed +46
The CREMA collaboration is pursuing a measurement of the ground-state hyperfine splitting (HFS) in muonic hydrogen (p) with 1 ppm accuracy by means of pulsed laser spectroscopy.…
Laser excitation of the 1s-hyperfine transition in muonic hydrogen
P. Amaro, A. Adamczak, M. Abdou Ahmed +43
The CREMA collaboration is pursuing a measurement of the ground-state hyperfine splitting (HFS) in muonic hydrogen (p) with 1 ppm accuracy by means of pulsed laser spectroscopy…
High-precision measurements of transition energies and level widths in He- and Be-like Argon Ions
J. Machado, C. I. Szabo, J. P. Santos +7
We performed a reference-free measurement of the transition energies of the line in He-like argon, and of the $1s 2s^2 2p\,^1P\_1\to 1s^2 2s^2\,^1S…
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…
