Abstract

The absolute mass value of 168Yb has been directly determined with the JYFLTRAP Penning trap mass spectrometer at the Ion Guide Isotope Separator On-Line (IGISOL) facility. A more precise value of the mass of 168Yb is needed to extract possible signatures of beyond standard model physics from high-precision isotope shift measurements of Yb atomic transition frequencies. The measured mass-excess value, (168Yb) = 61579.846(94) keV, is 13 times more precise and deviates from the Atomic Mass Evaluation 2016 value by 1.7σ. The impact on precision isotope shift studies of the stable Yb isotopes is discussed.
