Resonant photon scattering in the presence of external fields and its applications for the Gamma Factory
Jan Richter, Mieczyslaw Witold Krasny, Jan Gilles +1
This theoretical study explores resonant elastic photon scattering in the presence of external electric and magnetic fields, motivated by potential applications in storage ring exp…
Excited-state magnetic properties of carbon-like
Lukas J. SpieÃ, Shuying Chen, Alexander Wilzewski +13
We measured the -factor of the excited state in ion to be with a relative uncertainty of . The magnetic field…
Nonlinear calcium King plot constrains new bosons and nuclear properties
A. Wilzewski, L. I. Huber, M. Door +39
Nonlinearities in King plots (KP) of isotope shifts (IS) can reveal the existence of beyond-Standard-Model (BSM) interactions that couple electrons and neutrons. However, it is cru…
Quadratic Zeeman and Electric Quadrupole Shifts in Highly Charged Ions
Jan Gilles, Stephan Fritzsche, Lukas J. Spieà +2
Recent advances in high-precision spectroscopy of highly charged ions necessitate an understanding of energy shifts of ionic levels caused by external electric and magnetic fields.…
