Scientific Reference Information
Core Edge (Inner
Shell) Excitation Spectra of Gas-Phase Atoms and Molecules
From McMaster University, Canada, a searchable database and bibliography
of atomic and molecular core edge excitation oscillator strengths.
NIST Reference on constants, Units, and Uncertainty
This site from the National Institute of Standards and Technology
gives authoritative guidance regarding fundamental physical constants,
SI units, and the
uncertainty of
measurement results.
Periodic
Table
This site at the Illinois Institute of Technology's Center for Synchrotron
Radiation Research and Instrumentation shows x-ray properties of elements,
including cross-sections at specific energies.
SI Units
A handy reference to the Systéme Internationale d'unités, from
the Institute of Chemistry of the Freie Universität Berlin.
Synchrotron Light Source Data Book
Information about existing and planned light sources from NSLS.
WebElements
The periodic table of the elements, as presented by Mark Winter
of the University of Sheffield.
X-Ray Data Booklet
CXRO and the ALS publish this handy booklet, and much of the information is available from the
Web site as well. Order your own copy, or look up data about x-ray properties of elements,
synchrotron radiation, scattering, optics, and more.
X-Ray Interactions
with Matter
Atomic scattering factors, x-ray properties of elements, indexes of refraction,
attenuation lengths, transmission and reflectivity values, diffraction
efficiencies of transmission gratings, and calculations for bend magnet
radiation.
