Recommended Positron Scattering Cross Sections for Atomic Systems
Journal of Physical and Chemical Reference Data - Tập 48 Số 2 - 2019
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
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...
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
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...
Standard Reference Data for the Thermal Conductivity of Water
Journal of Physical and Chemical Reference Data - Tập 24 Số 3 - Trang 1377-1381 - 1995
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...
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
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...
The 1973 Least-Squares Adjustment of the Fundamental Constants
Journal of Physical and Chemical Reference Data - Tập 2 Số 4 - Trang 663-734 - 1973
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...
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
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...
Volumetric Properties of Aqueous Sodium Chloride Solutions
Journal of Physical and Chemical Reference Data - Tập 11 Số 1 - Trang 15-81 - 1982
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...
Phase Diagrams and Thermodynamic Properties of the 70 Binary Alkali Halide Systems Having Common Ions
Journal of Physical and Chemical Reference Data - Tập 16 Số 3 - Trang 509-561 - 1987
A 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’’ evalua...
Octanol-Water Partition Coefficients of Simple Organic Compounds
Journal of Physical and Chemical Reference Data - Tập 18 Số 3 - Trang 1111-1229 - 1989
Octanol-water partition coefficients (log P) for 611 simple organic compounds
representing all principal classes have been retrieved from the literature.
Available experimental details of measurement are documented from original
articles. Pertinent thermodynamic relations are presented, with a discussion of
direct and indirect methods of measurement. Reported log P data for each
compound have been...
