Extreme-ultraviolet spectroscopy using quantum logic: a feasibility study for the 1S-2S transition in singly-ionized helium
A. Martínez de Velasco, V. P. J. Barbé, E. L. Gründeman +11
Extreme-ultraviolet (XUV) spectroscopy represents an important new direction in precision physics, with potential applications ranging from the metrology of fundamental constants t…
Laser Excitation of the 1S-2S Transition in Singly-Ionized Helium
Elmer L. Gründeman, Vincent Barbé, Andrés Martínez de Velasco +6
Precision laser spectroscopy in the extreme ultraviolet of the 1S-2S two-photon transition in singly-ionized helium is a promising route for tests of fundamental physics. We demons…
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…
Muonic atom spectroscopy with microgram target material
A. Adamczak, A. Antognini, N. Berger +26
Muonic atom spectroscopy -- the measurement of the x rays emitted during the formation process of a muonic atom -- has a long standing history in probing the shape and size of nucl…
Demonstration of Ramsey-Comb Precision Spectroscopy in Xenon at Vacuum Ultraviolet Wavelengths Produced with High-Harmonic Generation
L. S. Dreissen, C. Roth, E. L. Gründeman +3
The remarkable progress in the field of laser spectroscopy induced by the invention of the frequency-comb laser has enabled many new high-precision tests of fundamental theory and…
Paving the way for fundamental physics tests with singly-ionized helium
J. J. Krauth, L. S. Dreissen, C. Roth +4
High-precision laser spectroscopy of atomic hydrogen has led to an impressive accuracy in tests of bound-state quantum electrodynamics (QED). At the current level of accuracy many…
