Abstract
We report an uncertainty evaluation of an optical lattice clock based on the transition in the bosonic isotope by use of magnetically induced spectroscopy. The absolute frequency of the transition has been determined through comparisons with optical and microwave standards at NIST. The weighted mean of the evaluations is . The uncertainty due to systematic effects has been reduced to less than , which represents in fractional frequency.
