Measurement of the $2$S${}_{1/2}-8$D${}_{5/2}$ transition in hydrogen

A. D. Brandt, S. F. Cooper, C. Rasor +3

We present a measurement of the hydrogen $2$S${}_{1/2}-8$D${}_{5/2}$ transition performed with a cryogenic atomic beam. The measured resonance frequency is $\nu =770649561570.9(2.0)$ kHz,…
