Schweiger, Christoph - Opis:
- In this Letter, we present mass-ratio measurements on highly charged Yb$^{42+}$ ions with a precision of 4 $\times$ 10$^{-12}$ and isotope-shift measurements on Yb$^{+}$ on the $^{2}S_{1/2} \to ^{2}D_{5/2}$ and $^{2}S_{1/2} \to ^{2}F_{7/2}$ transitions with a precision of 4 $\times$ 10$^{-9}$ for the isotopes $^{168,170,172,174,176}Yb$. We present a new method that allows us to extract higher-order changes in the nuclear charge distribution along the Yb isotope chain, benchmarking ab initio nuclear structure calculations. Additionally, we perform a King plot analysis to set bounds on a fifth force in the keV / c$^{2}$ to MeV / c$^{2}$ range coupling to electrons and neutrons.
