Abstract
In a crossed laser-atomic beam experiment the wavelengths of the transitions are measured in H and D to a precision of one part in . Our value for the Rydberg constant is . The fine-structure splittings of the states in H and D are 3249.8(8) and 3251.7(7) MHz, respectively; the isotope shifts for the and transitions are 124 260.7(7) and 124 262.6(7) MHz, respectively. Our results largely agree with previous, less precise experiments and with theory.
