Remeasurement of the Rydberg constant

We report a remeasurement of the Rydberg constant via a single-photon determination of the Balmer-$\alpha$ wavelength. The new value reflects the redefinition of the meter, a reexamination of corrections, and improvements of the experimental apparatus. The result is $R=109737.31569\mathrm{}\left(7\right)\mathrm{}$ ${\mathrm{cm}}^{-1\mathrm{}}$, where $c=299792458\mathrm{}$ m/s by definition. This result does not significantly disagree with the preceding measurement by Amin et al., significantly disagrees with the measurement by Hildum et al., and agrees very well with a recent measurement by Biraben and Julien.
