Present Status of the Fundamental Constants

Abstract

Since the completion of the authors’ 1973 least-squares adjustment of the fundamental constants [1], and its subsequent adoption for international use by the CODATA Task Group on Fundamental Constants and the 8th CODATA General Assembly [2], several relevant experiments and theoretical calculations have been completed. It is the purpose of this paper to examine the effect of some of these results, and in as far as possible, the effect of the most important new experiments and calculations reported at this Conference, on the recommended output values of our 1973 least-squares adjustment. It should be emphasized, however, that it is not our intention here to carry out a new adjustment nor to present an updated list of recommended values. Rather, we wish only to identify and examine the areas of major change which have occurred since 1973.
