 NIST XRay Form Factor, Attenuation and Scattering Tabulation
 Theoretical Form Factor, Attenuation, and Scattering Tabulation for Z = 192 from E = (110 eV) to (0.41.0 MeV). by C. T. Chantler (J. Phys. Chem. Ref. Data 24, 71 (1995)).
 NIST XRay Attenuation and Absorption for Materials of Dosimetric Interest
 By J. H. Hubbell and S. M. Seltzer, NIST. Tables and graphs of the photon mass attenuation coefficients and the mass energyabsorption 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 Database
 A 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=1100), at energies from 1 keV to 100 GeV.
 DABAX

DABAX (DAtaBAse for Xray applications) is a compilation of tables for xray applications with a collection of computer programs to access, visualize, and process these tables.
DABAX was created to unify the tabulated data (e.g., scattering factors and xray atomic cross sections) for different programs.
 Gas Phase Core Exitation Database
 Adam Hitchcock's database and bibliography at McMaster University.

 Web based calculations of scattering factors for dynamical xray diffraction and simulations of dynamical xray diffraction profiles from strained crystals and multilayers. Authored by Sergey Stepanov at the Advanced Photon Source.
 XOP
 XOP provides a set of codes from different authors and written in different computer languages for modeling of xray radiation sources and their interaction with xray optical components such as mirrors, filters, and multilayers and offers a variety of analyses and data visualizations.
