The gyromagnetic ratio of the proton

The quotient of the electromagnetic moment to the angular momentum, called the gyromagnetic ratio, would be calculable if to each element of mass was associated to a corresponding element of change, but as the value thus obtained turns out to be very different from the measured value, roughly 5.6 times smaller in the case of the proton, it is concluded that the knowledge of nuclei is not yet adequate for the calculation of the ratio. However, the behavior of the proton in a magnetic field leads to a simple method of measuring the gyromagnetic ratio. The method consists of observing the frequency of precession of protons in a known magnetic field and applying mechanics to obtain the results. The effect is analogous to that observed for a spinning top with its axis inclined to the vertical. The circuit and apparatus used for measuring the gyromagnetic ratio are described. (N.W.R.)
