Data provided by National Institute of Standards and Technology
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. XCOM provides two forms of output: (a) tables which correspond closely in format to existing tables in the literature; (b) graphical display of the tabular data. Access to the database is provided through a web-based form located at: http://physics.nist.gov/PhysRefData/Xcom/html/xcom1.html.
