Abstract: In this Letter, we present mass-ratio measurements on highly charged Yb42+ ions with a precision of 4×10-12 and isotope-shift measurements on Yb+ on the S21/2→D5/22 and S21/2→F7/22 transitions with a precision of 4×10-9 for the isotopes Yb168,170,172,174,176. 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/c2 to MeV/c2 range coupling to electrons and neutrons.
