Frequency evaluation of the doubly forbidden ${}^1{S}_0{\to }^3{P}_0$ transition in bosonic ${}^{174}$Yb

Abstract

We report an uncertainty evaluation of an optical lattice clock based on the ${}^1{S}_0{\leftrightarrow }^3{P}_0$ transition in the bosonic isotope ${}^{174}$Yb by use of magnetically induced spectroscopy. The absolute frequency of the ${}^1{S}_0{\leftrightarrow }^3{P}_0$ transition has been determined through comparisons with optical and microwave standards at NIST. The weighted mean of the evaluations is $\nu$(${}^{174}$Yb)=518 294 025 309 217.8(0.9) Hz. The uncertainty due to systematic effects has been reduced to less than 0.8 Hz, which represents $1.5\times 10^{-15}$ in fractional frequency.
