Precise frequency measurement of the 2S-8S/8Dtranstions in atomic hydrogen: New determination of the Rydberg constant

We have measured the Rydberg constant by frequency comparison of the three transitions 2${\mathit{S}}_{1/2\mathrm{\ensuremath{-}}}$8${\mathit{S}}_{1/2}$, 2${\mathit{S}}_{1/2\mathrm{\ensuremath{-}}}$8${\mathit{D}}_{3/2}$, and 2${\mathit{S}}_{1/2\mathrm{\ensuremath{-}}}$8${\mathit{D}}_{5/2}$ in hydrog...
