Recommended Positron Scattering Cross Sections for Atomic Systems
Journal of Physical and Chemical Reference Data - Tập 48 Số 2 - 2019
Kurunathan Ratnavelu, M. J. Brunger, S J Buckman
We 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 presented.
Comparison of Electron Elastic-Scattering Cross Sections Calculated from Two Commonly Used Atomic Potentials
Journal of Physical and Chemical Reference Data - Tập 33 Số 2 - Trang 409-451 - 2004
A. Jabłoński, F. Salvat, C. J. Powell
We 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 energies (1... hiện toàn bộ
Integral Cross Sections for Electron–Zinc Scattering over a Broad Energy Range (0.01–5000 eV)
Journal of Physical and Chemical Reference Data - Tập 49 Số 1 - 2020
R P McEachran, B P Marinković, G. Garcı́a, Ronald D. White, Peter W. Stokes, D. B. Jones, M. J. Brunger
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 data [Mar... hiện toàn bộ
Standard Reference Data for the Thermal Conductivity of Water
Journal of Physical and Chemical Reference Data - Tập 24 Số 3 - Trang 1377-1381 - 1995
M. L. V. Ramires, C. A. Nieto de Castro, Yuchi Nagasaka, Akira Nagashima, M. J. Assael, W. A. Wakeham
New 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 a previ... hiện toàn bộ
Franck–Condon Factors, r-Centroids, Electronic Transition Moments, and Einstein Coefficients for Many Nitrogen and Oxygen Band Systems
Journal of Physical and Chemical Reference Data - Tập 21 Số 5 - Trang 1005-1107 - 1992
Forrest R. Gilmore, Russ R. Laher, P. J. Espy
Air 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 spectrosco... hiện toàn bộ
The 1973 Least-Squares Adjustment of the Fundamental Constants
Journal of Physical and Chemical Reference Data - Tập 2 Số 4 - Trang 663-734 - 1973
Elaine Cohen, Barry N. Taylor
This 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 for int... hiện toàn bộ
CODATA Recommended Values of the Fundamental Physical Constants: 1998
Journal of Physical and Chemical Reference Data - Tập 28 Số 6 - Trang 1713-1852 - 1999
Peter J. Mohr, Barry N. Taylor
This paper gives the 1998 self-consistent set of values of the basic constants and conversion factors of physics and chemistry recommended by the Committee on Data for Science and Technology (CODATA) for international use. Further, it describes in detail the adjustment of the values of the subset of constants on which the complete 1998 set of recommended values is based. The 1998 set replaces its ... hiện toàn bộ
Optical Constants and Inelastic Electron-Scattering Data for 17 Elemental Metals
Journal of Physical and Chemical Reference Data - Tập 38 Số 4 - Trang 1013-1092 - 2009
Wolfgang Werner, Kathrin Glantschnig, Claudia Draxl
Two 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 functio... hiện toàn bộ

Volumetric Properties of Aqueous Sodium Chloride Solutions
Journal of Physical and Chemical Reference Data - Tập 11 Số 1 - Trang 15-81 - 1982
P. S. Z. Rogers, Kenneth S. Pitzer
Literature 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 the spec... hiện toàn bộ
