A search of the literature was made for the period from 1920 through June 1972, to obtain experimental x-ray cross sections for the elements in the energy range from 0.1 keV to 1 MeV. Total attenuation and photoelectric absorption data were evaluated and found not to be at variance with values reported in the compilation in the Final Report of this study. New experimental scattering data, along with earlier compiled experimental scattering data, were compared with theoretical values used in the compilation. Data are too scarce and errors are too large to evaluate the theoretical values unequivocally. Low energy theory was explored to determine whether changes in potential, or inclusion of relativistic or correlation effects could significantly improve calculated low energy cross sections. It was concluded that correlation effects would be most important.
