Finite Nuclear Size Corrections on Hyperfine Structure in Muonic Atoms
Doğa Yaşar, Bastian Sikora
Finite nuclear size (FNS) effects on the magnetic-dipole hyperfine splitting in muonic hydrogenlike ions are investigated within a fully relativistic Dirac framework. The FNS contr…
Two-loop electron self-energy in bound-electron factor: diagrams in momentum-coordinate representation
V. A. Yerokhin, B. Sikora, Z. Harman +1
The two-loop electron self-energy correction is one of the most problematic QED effects and, for a long time, was the dominant source of uncertainty in the theoretical prediction o…
Testing inter-electronic interaction in lithium-like tin
Jonathan Morgner, Vladimir A. Yerokhin, Charlotte M. Konig +9
Magnetic moments of bound-electron systems are a sensitive tool for testing fundamental interactions. factors of lithium-like ions have been rigorously studied in recent years,…
Factor of Boron-like Tin
J. Morgner, B. Tu, M. Moretti +10
In the ALPHATRAP experiment, the factor of boron-like has been measured with a parts-per-billion uncertainty. This is the first high-precision m…
Improved bound-electron g-factor theory through complete two-loop QED calculations
Bastian Sikora, Vladimir A. Yerokhin, Christoph H. Keitel +1
The two-loop self-energy correction to the bound-electron -factor in hydrogenlike ions is investigated, taking into account the electron-nucleus interaction exactly. This all-or…
Vacuum Polarization Effects in the Hyperfine Splitting of Hydrogen Like Ions
Junis Heiland Hoyo, Bastian Sikora
The hyperfine structure of bound electrons in hydrogen-like ions is considered with corrections to the energy levels due to vacuum polarization (VP). Corrections to the wave functi…
Precision spectroscopy on Be overcomes limitations from nuclear structure
Stefan Dickopf, Bastian Sikora, Annabelle Kaiser +7
Many powerful tests of the Standard Model of particle physics and searches for new physics with precision atomic spectroscopy are plagued by our lack of knowledge of nuclear proper…
Impact of the nuclear charge distribution on the g-factors and ground state energies of bound muons
Atakan Çavuşoğlu, Bastian Sikora
The finite nuclear size corrections to the ground state energies and g-factors in muonic atoms are investigated for several elements. Both approximative and exact solutions of the…
Direct measurement of the He magnetic moments
A. Schneider, B. Sikora, S. Dickopf +10
Helium-3 has nowadays become one of the most important candidates for studies in fundamental physics [1, 2, 3], nuclear and atomic structure [4, 5], magnetometry and metrology [6]…
Muonic vacuum polarization correction to the bound-electron -factor
N. A. Belov, B. Sikora, R. Weis +5
The muonic vacuum polarization contribution to the -factor of the electron bound in a nuclear potential is investigated theoretically. The electric as well as the magnetic loop…
