Abstract
Differential cross sections for the elastic scattering of γ-rays for energies between 145 keV and 750 keV and for charge numbers from 30 to 82 are presented for scattering angles ranging from 45° to 135°. These differential cross sections have been calculated using form factors and “corrected form factors” obtained from relativistic HFS wave functions and using a semi- empirical procedure for obtaining accurate scattering amplitudes from the form factors. For an easy extension of the tabulation, exact analytical expressions based on relativistic hydrogen wave functions are presented for both form factors and all subshells of the atom. Effective charge numbers are given providing close agreement between form factors calculated from relativistic hydrogen wave functions and from relativistic HFS wave functions.
