Atomic Masses and Fundamental Constants 6, Softcover reprint of the original 1st ed. 1980

Langue : Anglais

Coordonnateur : Nolen Jerry A.

Couverture de l’ouvrage Atomic Masses and Fundamental Constants 6
The Sixth International Conference on Atomic Masses was held in East Lansing, Michigan, Sept. 18-21, 1979. The conference was initiated, organized, and sponsored by the Commission on Atomic Masses and Fundamental Constants of the International Union of Pure and Applied Physics. The members of the conference committee are listed below: W. Benenson, Chairman Michigan State University R. C. Barber University of-Manitoba E. R. Cohen Rockwell International Institute of Chemical Physics, V. I. Goldanskii Moscow J. C. Hardy Chalk River, Canada W. H. Johnson University of Minnesota E. Kashy Michigan State University Orsay, France R. Klapisch J. A. Nolen, Jr. Michigan State University R. G. H. Robertson Michigan State University E. Roeckl G. S. I. , Darmstadt B. N. Taylor National Bureau of Standards O. Schult IKF, Julich A. H. Wapstra IFO, Amsterdam N. Zeldes Racah Institute, Jerusalem The conference was a little different from the preceding one (in Paris, 1975) in that the fundamental constant aspects were limited to those directly related to atomic masses. The gap is to be filled by the second International Conference on Precision Measurement and Fundamental Constants which is now scheduled for June 1981 in Gaithersburg, Maryland. Only one of the seven sessions in this conference was devoted to fundamental constant determina­ tions. The conference was very strongly supported by the Department of Energy, the National Science Foundation, and the International Union of Pure and Applied Physics.
