Excluding Hypothetical Light Boson Interpretation of Yb King Plot Nonlinearity with the ${}^1{S}_0\leftrightarrow {}^3{P}_2$ Isotope Shift Measurement

Taiki Ishiyama, Koki Ono, Reiji Asano +6

We present precision spectroscopy and isotope shift measurement of the ${}^1{S}_0\leftrightarrow {}^3{P}_2$ clock transition in neutral ytterbium ($\mathrm{Yb}$) atoms. By revealing a…
