摘要：

We have compared the frequency of the hydrogen 1S-2S transition (resonance width DELTAnu/nu=2.8 x 10(-11)) with a reference frequency synthesized from an 88-THz infrared CH4-stabilized HeNe laser. In this first measurement of an optical frequency that overcomes the uncertainty limits of the visible I2-stabilized He-Ne laser standard, we find a 1S-2S frequency of 2466061413.182(45) MHz with an 18-fold improved precision of 1.8 parts in 10(11). A new value of the Rydberg constant, R(infinity) = 109737.3156841(42) cm-1, is deduced.
