X-Ray Reference Data
- NIST Attenuation Coefficient Bibliography
- References to measured photoabsorption cross-sections compiled by John Hubbell at NIST.
- NIST X-Ray Form Factor, Attenuation and Scattering Tabulation
- Theoretical Form Factor, Attenuation, and Scattering Tabulation for Z = 1-92 from E = (1-10 eV) to (0.4-1.0 MeV). by C. T. Chantler (J. Phys. Chem. Ref. Data 24, 71 (1995)).
- NIST X-Ray 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 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 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=1-100), at energies from 1 keV to 100 GeV.
- Elastic Photon-Atom Scattering
- Theoretical 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 Server
- Presently, 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.
- Gas Phase Core Exitation Database
- Adam Hitchcock's database and bibliography at McMaster University.
X-Ray Programs
- IMD
- Multilayer optical properties: modeling and curve-fitting IDL package written by David Windt.
- Sergey's X-Ray Library
- Web 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 Routines
- IDL 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
- 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).
