我们通过比较氢气中的三个跃迁2S 1/2 -8S 1/2 、2S 1/2 -8D 3/2 和2S 1/2 -8D 5/2 的频率与甲烷稳定氦氖激光器和碘稳定氦氖激光器这两种光学标准的差异来测量里德伯常数。重新测量了碘稳定氦氖激光器的频率。里德伯常数的新值 R ∞=109 737.315 6830(31) cm -1 是目前最精确的可用值
We have measured the Rydberg constant by frequency comparison of the three transitions 2S 1/2 -8S 1/2 , 2S 1/2 -8D 3/2 , and 2S 1/2 -8D 5/2 in hydrogen with the difference of two optical standards, the methane-stabilized He-Ne laser and the iodine-stabilized He-Ne laser. The frequency of the iodine-stabilized He-Ne laser has been remeasured. The new value for the Rydberg constant, R ∞=109 737.315 6830(31) cm -1 , is currently the most precise available
