DOIAbstract
We report an uncertainty evaluation of an optical lattice clock based on the S01↔P03 transition in the bosonic isotope Yb174 by use of magnetically induced spectroscopy. The absolute frequency of the S01↔P03 transition has been determined through comparisons with optical and microwave standards at NIST. The weighted mean of the evaluations is ν(Yb174)=518294025309217.8(0.9)Hz. The uncertainty due to systematic effects has been reduced to less than 0.8Hz, which represents 1.5×10−15 in fractional frequency
