摘要：

An optical frequency chain referenced to a Cs atomic clock has been used to measure directly the frequency of the electric quadrupole allowed 5s(2)S(1/2) - 4d(2)D(5/2) transition at 445 TI-Iz in a single, trapped, and laser cooled Sr-88(+) ion. A transition frequency, f(S-D) = 444779044095.4 kHz with an estimated standard uncertainty of 0.2 kHz has been determined. Intrinsic offsets of the probed ion transition in the current experiment are calculated to be at the 10(-15) level. [S0031-9007(99)08942-5].
