Abstract

The Committee on Data for Science and Technology (CODATA) was established in 1966 as an interdisciplinary committee of the International Council of scientific Unions (now International council of Science). Three years later, CODATA created the task group on fundamental constants to periodically provide the scientific and technological communities with a self-consistent set of internationally recommended values for the basic constants and conversion factors of physics and chemistry. Under the auspices of the task group, we have completed a new least-squares adjustment of those values - termed the 2006 adjustment - that takes into account all relevant data available through 31 December 2006. The accompanying tables give the 2006 CODATA recommended values resulting from that adjustment, except for some specialized x-ray-related quantities and various natural and atomic units. The complete 2006 CODATA set of more that 300 recommended values, together with a detailed description of the data and their analysis, is given in reference 1. All of the values as well as the correlation coefficients between any two constants, are available online in a searchable database provided by the NIST fundamental constants data center. the URL is http://physics.nist.gov/constants.
