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 '.

States with only a one or two star (*) rating in that list have been omitted from the main Baryon Table; each omitted st*te is indicated by an arrow in the left-hand margin of the Table. In the Listings there is an arrow under the name of each state omitted from the Table. The names of the Baryon States in Col. 1 [such as N(1470)] contain a nominal mass which is primarily for purposes of identification. See Col. 4 for actual mass values. The convention for using primes in the spectroscopic notation for the quantan numbers in Col. 2 (such as pjjl is as follows: no prime is attached when the Data Card Listings include only one resonance in the given partial wave; when there is more than one resonance the first has been designated with a prime, the second with a double prime, etc. The name and the quantum numbers for each state are also qiven in large print at the beginning of the Data Card Listings for that state. See footnote a. of the Stable Particle Table for the strangen&ss quantum numbers of the baryons; in addition to the names listed there, we also use H and A for S = 0 baryons, and z* for s =+1 baryons. The numbers in Col. 3 and Col. 6 are calculated using the nominal mass (see <>. above) for H and the nominal width (see o. below) for T. For masses, widths, and branching fractions of most baryons we report here a range instead of an average. Averages are appropriate if each result is based on independent measurements, but inapprop riate where the spread in parameters arises because different models or procedures have been applied to a common set of data. The ranges given in the Table are generally chosen to be conservativel3 particles we give the maximum moment1 an, £,„„» that any of the particles in the final state can have in this frame. The momenta are calculated using the nominal mass (see o. above) of the decaying baryon, and of any isobars in the final state. Some decays which would be energetically forbidden for the nominal masses actually occur because of the finite widths of the decaying baryon and/or isobars in the final state. In these cases, th*» decay momentum is omitted from Col. 9 and replaced with a reference to this footnote. Square brackets around an isobar decay mode indicate that it is a sub-reaction of the previous unbraclceted decay mode. Many of the branching fractions in the Table are extracted from significantly more accurate results on vxx* type couplings obtained in partial-wave analyses. The original Vxx' values are given in the Baryon Data Card Listings. For information on radiative decays of N's and A's, se PHYSICAL CONSTANTS „, , Uncert.

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 of the main number. The equivalent uncertainty In parts per million (ppm) is given in the last column. Note that the uncertainties of the output values of 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 of Cohen and Taylor has been recommended for international use by C0DATA (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 097Bi63)Kl 1/2 * 1/2 ,V2 i r,S<,.

Figure indicates total path length; observed range may be smaller (by - i% - 2% in heavy elements) due to multiple scattering, primarily from small energy-loss collisions with nuclei.

This range is the total path length; the practical range is shorter because of multiple Coulomb scat tering, whit h becomes increasingly important as the electron slows down. K.g. , for a fast electron the rms projected angle due to multiple Coulomb scattering reaches 1 radian by the time the electron has slowed tc. 0.4 MeV in hydrogen, 1,5 M€-V in carbon, 9 MeV in copper, and 24 MeV (off scale) in lead. Th*- "/ ritira] energy" (above which the energy loss due to brem sstrahlung exceeds that due to ionization,and showering becomes important) is 400 MeV for hydrogen, 100 MeV for carbon, 2T MeV for copper, and ]0 MeV for lead. The mean positron range may differ from the rtiean electron range by several percent. See Bergcr and Selt/.er, NASA SP- 3012 (1964) and S P- 3036 , and P.

Tor a homogeneous mediun of density o, the intensity I remaining after traversal of thickness t is given by I= I exp(-Ut). The accuracy is a few percent. Interpolation to other Z should be done in the cross 2 section r, = (u/c) M/Nn cm /atom, where M is the atomic weight of the absorber material and NA is Avogadro's number. For a chemical compound or mixture, use lu/o)eff ^ £ wi(U/p)£ , accurate to a few percent, where wi is the proportion by weight of the ith constituent. The dashed curve is the mass energy- absorption coefficient, giving u/p multiplied by the fraction of photon energy deposited in a small volume (assumed large enough to contain the ranges of most secondary electrons) about the interaction. This fraction is smaller than 1.0 because such processes as Compton scatterina and electron bretnsstrahlung imply radiation of some of the energy away from the immediate- area. From J. H.

(>) t'-x': Section VI B.2 I can be neglected for K , because it is proportional to the lepton mass. The f+ term is usually assumed to be linear in t = q'= (P - P_T/ the square of the four-momentum transfer, i.e., the effective mass of the lepton • jir. We quote the linear coefficient / (L+E on the data cards). There has been some suggestion of departure from linearity [CHIEN 71 (K°_) and Chounet, Gaillard, 1 G and Gaillard — P.eview] but no compelling evidence. The A+ results are fairly consistent and the average values are K+ = X = 0.0285 i 0.0043 e3 + K0,: A = 0.0300 ± 0.001E (5=1.2) e3 + where the K° error has been multip1ied by the scale factor 1.2 to compensate for inconsistencies (see ideogram in K section L+E).
