Experimental x-ray attenuation cross sections for 94 elements between 0.1 keV and 1 MeV were obtained for the period from 1920 through 1970. Exact photoelectric absorption values also were calculated for hydrogen. Scattering cross sections were calculated by relativistic SCF methods. These were subtracted from total attenuation data, and the the resulting photoelectric and measured photoelectric absorption cross sections from 1 keV to 1 MeV were fit by a least squares procedure to obtain best values. Interpolations were made for elements and energy ranges for which there were no experimental data. From 0.1 keV to between 1 keV and 10 keV non-relativistic, self-consistent, independent electron theory was used to calculate photoelectric absorption cross sections. Scattering values were added to all photoelectric cross sections to obtain a best set of attenuation cross sections. (auth)
