我们报道了<sup> </sup>S<sub>1/2</sub> (F =0, m<sub>F</sub>=0)-<sup>2</sup>F<sub>7/2</sub> (F =3, m<sub>F</sub>=0)单个被捕获激光冷却离子<sup >71 </sup>Yb<sup>+</sup>的时钟跃迁的精确激光光谱。测量到的绝对频率为642 121 496 772 656 (12)Hz，比以前的测量精度提高了20倍。
We report precision laser spectroscopy of the <sup>2</sup>S<sub>1/2</sub> (F = 0, m<sub>F</sub>=0)-<sup>2</sup>F<sub>7/2</sub> (F =3, m<sub>F</sub>= 0) clock transition in a single, trapped, laser cooled ion of <sup>171</sup>Yb<sup>+</sup>. The absolute frequency is measured to be 642 121 496 772 656 (12) Hz, a factor of 20 more accurate than previous measurements.
