摘要：

We report what we believe to be the first accuracy evaluation of an optical lattice clock based on the S-1(0) -> P-3(0) transition of an alkaline earth boson, namely, Sr-88 atoms. This transition has been enabled by using a static coupling magnetic field. The clock frequency is determined to be 429 228 066 418 009 (32) Hz. The isotopic shift between Sr-87 and Sr-88 is 62 188 135 Hz with fractional uncertainty 5 x 10(-7). We discuss the necessary conditions to reach a clock accuracy of 10(-17) or less by using this scheme. (c) 2007 Optical Society of America.
