Résumé
We present a new evaluation of an <SUP>87</SUP>Sr optical lattice clock using spin polarized atoms. The frequency of the <SUP>1</SUP>S<SUB>0</SUB>--><SUP>3</SUP>P<SUB>0</SUB> clock transition is found to be 429 228 004 229 873.6 Hz with a fractional uncertainty of 2.6×10<SUP>-15</SUP>, a value that is comparable to the frequency difference between the various primary standards throughout the world. This measurement is in excellent agreement with a previous one of similar accuracy [Phys. Rev. Lett. 98, 083002 (2007)].
