Abstract

We report on the evaluation of an optical lattice clock using fermionic ⁸⁷Sr. The measured frequency of the ¹S₀ → ³P₀ clock transition is 429 228 004 229 873.7Hz with a fractional acuracy of 2.6 × 10^-15. This evaluation is performed on m_F = ±9/2 spin-polarized atoms. This technique also enables to evaluate the value of the differential Landé factor, 110.6Hz/G. by probing symmetrical σ-transitions.
