Probing New Bosons and Nuclear Structure with Ytterbium Isotope Shifts

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 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...
