A Re-Evaluation of the Fundamental Atomic Constants

Abstract

A completely new evaluation of the fundamental atomic constants by the method of least squares is presented. A number of new and highly precise experiments have been taken into account, including the measurement of: (1) the velocity of light by an exceptionally ingenious and precise method due to Hansen and Bol, (2) the absolute proton moment, (3) the ratio of magnetic moments of proton and electron, (4) the proton moment in Bohr magnetons, (5) the hyperfine structure separation of ground-state hydrogen, (6) the ratio of cyclotron to precession frequency of the proton, (7) $\frac{h}{\mathrm{mc}}$ using annihilation radiation, and (9) $\frac{h}{e}$ from the x-ray high frequency limit with improved precision.
