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…
Probing new bosons and nuclear structure with ytterbium isotope shifts
Menno Door, Chih-Han Yeh, Matthias Heinz +24
In this Letter, we present mass-ratio measurements on highly charged Yb ions with a precision of and isotope-shift measurements on Yb on the …
Atomic mass determination of uranium-238
Kathrin Kromer, Chunhai Lyu, Jacek Bieroń +10
The atomic mass of uranium-238 has been determined to be , improving the literature uncertainty by two orders of magnitude. It is obtained from a m…
Observation of a low-lying metastable electronic state in highly charged lead by Penning-trap mass spectrometry
Kathrin Kromer, Chunhai Lyu, Menno Door +10
Highly charged ions (HCIs) offer many opportunities for next-generation clock research due to the vast landscape of available electronic transitions in different charge states. The…
High-precision determination of factors and masses of and
F. Heiße, M. Door, T. Sailer +13
We present the measurements of individual bound electron factors of and on the relative level of per billion. Th…
A Digital Feedback System for Advanced Ion Manipulation Techniques in Penning Traps
Jost Herkenhoff, Menno Door, Pavel Filianin +7
The possibility to apply active feedback to a single ion in a Penning trap using a fully digital system is demonstrated. Previously realized feedback systems rely on analog circuit…
