Excerpt
Introduction: The Commission on Atomic Weights and Isotopic Abundances met under the chairmanship of Professor K. G. Heumann from 4'h-6'h August 1995, during the 38 IUPAC General Assembly in Guildford, United Kingdom. The Commission decided to publish the report Atomic Weights of the Elements 1995 as presented here and the report Isotopic Compositions of the Elements 1995.' The Commission has reviewed the literature over the previous two years since the last report on atomic weights and evaluated the published data on atomic weights and isotopic compositions on an element-by-element basis. The atomic weight, Ar(E), of element E can be determined from a knowledge of the isotopic abundances and corresponding atomic masses of the nuclides of that element. The last compilations of the isotopic abundances and atomic masses with all relevant data were published in 1991 and 1993 respectively. The Commission periodically reviews the history of the atomic weight of each element emphasizing the relevant published?
