Recommended Positron Scattering Cross Sections for Atomic SystemsWe present a critical analysis of available experimental and theoretical cross section data for positron scattering from atomic systems. From this analysis, we present (where data are available) recommended cross sections for total scattering, positronium formation, inelastic scattering, and direct ionization processes. A complete bibliography of available measurement and theory is also pr...

Comparison of Electron Elastic-Scattering Cross Sections Calculated from Two Commonly Used Atomic PotentialsWe have analyzed differential cross sections (DCSs) for the elastic scattering of electrons by neutral atoms that have been derived from two commonly used atomic potentials: the Thomas–Fermi–Dirac (TFD) potential and the Dirac–Hartree–Fock (DHF) potential. DCSs from the latter potential are believed to be more accurate. We compared DCSs for six atoms (H, Al, Ni, Ag, Au, and Cm) at four ene... ...

Integral Cross Sections for Electron–Zinc Scattering over a Broad Energy Range (0.01–5000 eV)We report results from the application of our optical potential and relativistic optical potential methods to electron–zinc scattering. The energy range of this study was 0.01–5000 eV, with original results for the summed discrete electronic-state integral excitation cross sections and total ionization cross sections being presented here. When combined with our earlier elastic scattering d... ...

Standard Reference Data for the Thermal Conductivity of WaterNew experimental data on the thermal conductivity of liquid water along the saturation line have been obtained recently, using the bare and coated transient hot wire technique, with high accuracy. The quality of the data is such that new standard reference values can be proposed with confidence limits of 0.7% at a 95% confidence level. These data and the correlation herein presented revise... ...

Franck–Condon Factors, r-Centroids, Electronic Transition Moments, and Einstein Coefficients for Many Nitrogen and Oxygen Band SystemsAir fluorescence models require accurate Franck–Condon factors and Einstein coefficients for analyzing the intensities of N2, N+2, and O+2 emissions produced by electron bombardment of air, such as in the aurora, high-altitude nuclear explosions, and rocket-borne electron gun experiments. In our previous report, improved vibrational and rotational constants based on the latest available sp... ...

The 1973 Least-Squares Adjustment of the Fundamental ConstantsThis paper is a summary of the 1973 least-squares adjustment of the fundamental physical constants carried out by the authors under the auspices of the CODATA Task Group on Fundamental Constants. The salient features of both the input data used and its detailed analysis by least-squares are given. Also included is the resulting set of best values of the constants which is to be recommended... ...

Optical Constants and Inelastic Electron-Scattering Data for 17 Elemental MetalsTwo new sets of optical data, i.e., values for the real (ε1) and imaginary (ε2) parts of the complex dielectric constant as well as the energy loss function (ELF) (Im{−1∕ε}), are presented for 16 elemental metals (Ti, V, Fe, Co, Ni, Cu, Zn, Mo, Pd, Ag, Ta, W, Pt, Au, Pb, and Bi) and 1 semimetal (Te) and are compared to available data in the literature. One data set is obtained from density... ...

Volumetric Properties of Aqueous Sodium Chloride SolutionsLiterature data for the volumetric properties of sodium chloride solutions to concentrations of 5.5 molal have been compiled and critically evaluated. A semi-empirical equation of the same type found to be effective in describing the thermal properties of NaCl solutions has been used to reproduce the volumetric data from O °C to 300 °C and 1 bar to 1000 bar. Tables of values are given for ... ...

Phase Diagrams and Thermodynamic Properties of the 70 Binary Alkali Halide Systems Having Common IonsA very extensive literature survey of all available phase diagram and thermodynamic data has been carried out for all 40 possible common-anion binary systems (AX-BX) and all 30 possible common-cation binary systems (AX-AY) involving the alkali halides (A,B =Li,Na,K,Rb,Cs; X,Y=F,Cl,Br,I). A critical analysis and evaluation of these data have been performed with a view to obtaining a ‘‘best’... ...
