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${}^{42+}$ ions with a precision of $4\times 10^{-12}$ and isotope-shift measurements on Yb${}^{+}$ on the ${}^2$…
