Description A recently reported study [Phys. Rev. A49, 3664 (1994)] of elastic scattering of 81 keV gamma rays in the angular range from 60 degrees to 133 degrees has been extended to smaller and larger angles. Previously reported S matrix calculations of atomic Rayleigh scattering have been shown to require a subtraction of contributions from spurious resonances. Most of the experimental data are in agreement with the calculations. Calculations (MF + ASF) based on a combination of relativistic modified form factors (MF's) and angle independent anomalous scattering factors (ASF's) are found to be inadequate for an explanation of experimental cross-sections in the case of high Z elements at angles larger than about 120 degrees.
