Relativistic Dirac-Hartree-Fock photon incoherent scattering functions

The incoherent scattering function S for photons was calculated in the relativistic treatment of Ribberfors and Berggren, using Dirac-Hartree-Fock relativistic wavefunctions. Tables of S, for Z = 1-110, are presented on a momentum transfer mesh identical to previous nonrelativistic calculations. S has been calculated at a representative scattering angle of theta = 60 degrees and energies compatible with the presentation mesh. For other scattering angles, the values presented in the tables are accurate to within 1-2% for momentum transfers larger than 0.1 Angstrom(-1). In the region below 0.1 Angstrom(-1) the accuracy worsens with decreasing momentum transfer, reaching 6% at 0.01 Angstrom(-1) and 10% at 0.005 Angstrom(-1). (C) 1998 Academic Press.
