WEBElement/Compound/Mixture Selection. In this database, it is possible to obtain photon cross section data for a single element, compound, or mixture (a combination of elements and compounds). Please fill out the following information: Help. Identify material by: ElementCompoundMixture. Method of entering additional energies: (optional)
WEBSep 17, 2009 · Abstract. A web database is provided 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 ≤ 100), at energies from 1 keV to 100 GeV.
WEBThe XCOM program can generate cross sections on a standard energy grid (spaced approximately logarithmically), or on a grid selected by the user, or for a mix of both grids. Cross sections at energies immediately above and below all absorption edges are automatically included.
WEBNIST XCOM: Photon Cross Sect. Database - Using the Program. 4. How to Run the XCOM Program. 4.1. Overview. There are two ways to use the XCOM database. The text-based version outputs a basic text table of data. The other version gives the user more options and features (e.g., file-uploading, graphing, and graphical tables).

WEBInterpolation and Combination. For the purpose of interpolation with respect to photon energy, the coherent and incoherent scattering cross sections and the total attenuation coefficients are approximated by log-log cubic-spline fits as functions of energy.
