Abstract : Accurate predictions of cross section for the photoeffect can at present only be obtained with numerical methods. Such calculations for the K shell were made by Hulme et.al. for 3 elements and 2 energies and more recently by Hultberg, Nagel, and Olsson (HNO) for a series of energies in 2 heavy elements. Results are presented which have extended these calculations to encompass the range of elements from Z=13 to Z=92 and of energies from 200 keV to 2 MeV, obtaining differential and total cross sections and all polarization correlations between incoming photon and ejected electron. The numerical methods used here are more general than those of previous calculations and will permit inclusion of the screening effects of outer electrons. (Author)
