A saturated absorption spectroscopy measurement of the Rydberg constant
A tuneable dye laser saturated absorption measurement of three of the fine-structure components of the Balmer alpha line of atomic hydrogen in a gas discharge yields a value of 10, 973, 731.513(85)… Expand
A measurement of the Rydberg constant
THE Rydberg constant is of key importance in spectroscopy and, because it may be expressed as the product of several fundamental physical constants, it also plays an important part as an auxiliary… Expand
A precise omegatron measurement of μp/μ N
The value obtained for the proton magnetic moment in nuclear magnetons was 2.7927748+or-0.0000020 (0.72 ppm) without the diamagnetic shielding correction. Measurements were made with a quadrupole… Expand
A Measurement of 2e/h by the ac Josephson Effect
2 e/h has been measured using the ac Josephson effect at 36 GHz and the solder-drop type of junction. The final result is that 2 e/h is 483.5941 ± 0.0010 (2.2 in 106) MHz/μ VNPL 1969. If the 1967… Expand
Moulded microwave squid for r.f.-attenuator calibration
The letter describes the use of a moulded microwave SQUID which has been used to calibrate a high-precision waveguide-beyond-cutoff (w.b.c.o.) r.f. attenuator with an accuracy of 0.0024 dB (s.d.).
A MEASUREMENT OF $mu$/sub p//$mu$/sub N/ WITH A QUADRUPOLE OMEGATRON.
New Determination of the Magnetic Moment of the Proton in Terms of the Nuclear Magneton
THE ratio of f s the spin precession frequency of the proton, to f c , the cyclotron frequency, in the same magnetic field is equal to the ratio of the magnetic moment of the proton μ p to the… Expand
Precision Measurement of p/N
WE report here the results of a precision measurement of the ratio of the magnetic moment of the proton µN to that of the nuclear magneton µp. The importance of such a determination derives from the… Expand
