NIST X-Ray Attenuation and Absorption for Materials of Dosimetric InterestBy J. H. Hubbell and S. M. Seltzer, NIST. Tables and graphs of the photon mass attenuation coefficients and the mass energy-absorption coefficients from 1 keV to 20 MeV are presented for all of the elements (Z = 1 to 92) and for 48 compounds and mixtures of radiological interest.
XCOM: Photon Cross Sections DatabaseA web database which can be used to calculate photon cross sections for scattering, photoelectric absorption and pair production, as well as total attenuation coefficients, for any element, compound or mixture (Z=1-100), at energies from 1 keV to 100 GeV.
Elastic Photon-Atom ScatteringTheoretical calculations of the forward atomic scattering factors, elastic scattering cross sections, and angle dependence of the scattering factors, for photon energies up to 10 MeV. by Lynn Kissel and Paul Bergstrom at LLNL.
ESRF DABAX ServerPresently, this DABAX server provides data for photon-atomic scattering, photon-atomic scattering factors (dispersive and non-dispersive parts) from different authors. It also provides other atomic constants (x-ray emission and absorption energies, atomic weights, etc…). Several files for XAFS are also provided.
IMDMultilayer optical properties: modeling and curve-fitting IDL package written by David Windt.
Sergey’s X-Ray LibraryWeb based calculations of scattering factors for dynamical x-ray diffraction and simulations of dynamical x-ray diffraction profiles from strained crystals and multilayers. Authored by Sergey Stepanov at the Advanced Photon Source.
Stony Brook IDL RoutinesIDL routines which calculate the complex index of refraction for a material from the atomic scattering factors. The output of these routines may be then used in the calculation of other quantities such as the transmission of a filter, etc. A routine to calculate reflectivity is also available. Written by Chris Jacobsen.
XOP is a widget based interface which drives different programs that calculates the synchrotron radiation source spectra (bending magnet, wigglers and undulators) and the reflection and transmission characteristics of optical elements as: mirror, filters, flat crystals, bent perfect crystals, and multilayers. XOP is the result of a collaboration work between Manuel Sanchez del Rio (ESRF) and Roger J. Dejus (APS).
