Graphs of calculated and experimental atomic photoeffect cross sections as a function of photon energy 0.1 keV to 1.5 MeV are presented for all elements Z /sup =/ 1 to 94. The calculated results presented are the non-relativistic Hartree--Fock self-consistent-field (SCF) results of Veigele, Henry, et al., over the range 0.1 keV to between 1.0 and 8.0 keV for all elements Z /sup =/ 1 to 94 and the relativistic Hartree--Slater SCF results of Scofield over the range 1.0 keV to 1.5 MeV for all elements Z /sup =/ 1 to 101. The 'experimental' data- points are derived by subtracting theoretical scattering cross sections from total attenuation coefficient measurements in the literature. Differences between theoretical and experimental photoeffect data are typically a factor of two from 0.1 to 1.0 keV, 5 to 10% from 1.0 to 5.0 keV, and 1 to 5% from 5.0 keV up to energies, ranging from 20 keV for carbon up to 500 keV for lead, above which the photoeffect cross section becomes fractionally too small to be accurately determined from the total attenuation coefficient.
