Taylor. Originally prepared by Stanley J. Brodsky, based mainly on the "1973 Least-Squares Adjustment of the Fundamental Constants," by E. R. Cohen and B. N. Taylor, J. Phys. Chem. Ref. Data 2, 663 (1973). The figures in parentheses correspond to the one-standard-deviation uncertainty in the last digits or the main number. The equivalent uncertainty in parts per million (ppm) is given in the last column. Note that the uncertainties or the output values or a least-squares adjustment are in general correlated, and the general law of error propagation must be used in calculating additional quantities. The set of constants resulting from the 1973 adjustment or Cohen and Taylor has been recommended for international use by CODATA (Committee on Data for Science and Technology), and is the most up-to-date, generally accepted set currently available. However, since the publication of the 1973 adjustment, a number of new experiments have been completed, yielding improved values for some of the constants: NA - 6.022 097 8(63)xl083 mole"1 (1.04 ppm); a'1 - 137.035 987(29) (0.21 ppm) (obtained using the Josephson effect J; and R„ - 109 737.3143(10) cm-1 (0.009 ppm). [See Atomic Masses and Fundamental Constants 5, Ed. by J. H. Sanders and A. H. Wapstra, Plenum Pub. Co., (1976).) But it must be realized that, since the output values of a least-squares adjustment are related in a complex way and a change in the measured value of one constant usually leads to corresponding changes in the adjusted values of others, one must be cautious in carrying out calculations using both the output values from the 1973 adjustment and the results of more recent experiments. A new adjustment Is planned for completion in 1980. Volume 75B PHYSICS I I I II US 24 April l'PX REVIEW Of PARTICLE PROPERTIES Panicle Data (.roup (". URICMAN. f'. IJIOMSI. K.J. Ill MINGWAY '.
