| Abstract [eng] | In this Letter, we present mass-ratio measurements on highly charged Yb42þ ions with a precision of 4 × 10−12 and isotope-shift measurements on Ybþ on the 2S1/2 → 2D5=2 and 2S1/2 → 2F7=2 transitions with a precision of 4 × 10−9 for the isotopes 168;170;172;174;176Yb. 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. |
