Abstract-Several models for the simulation of photon elastic scattering are quantitatively evaluated with respect to a large collection of experimental data retrieved from the literature. They include models based on the form factor approximation, on S-matrix calculations and on analytical parameterizations; they exploit publicly available data libraries and tabulations of theoretical calculations. Some of these models are currently implemented in general purpose Monte Carlo systems; some have been implemented and evaluated for the first time in this paper for possible use in Monte Carlo particle transport. The analysis mainly concerns the energy range between 5 keV and a few MeV. The validation process identifies the newly implemented model based on second order S-matrix calculations as the one best reproducing experimental measurements. The validation results show that, along with Rayleigh scattering, additional processes, not yet implemented in Geant4 nor in other major Monte Carlo systems, should be taken into account to realistically describe photon elastic scattering with matter above 1 MeV. Evaluations of the computational performance of the various simulation algorithms are reported along with the analysis of their physics capabilities.

Incoherent scattering functions were determined experimentally for a photon energy of 59.5 keV at an angle 110° for the elements V, Cr, Co Br, Sr, Cd, I, Cs, Ba, Ce, Nd, Sm, Hf, Os and Tl using a high‐resolution Ge(Li) detector. The experimental values of incoherent scattering functions at the momentum transfer x ≈ 2.74 Å−1 were compared with those estimated on the basis of the non‐relativistic Hartree–Fock wavefunctions. The present results were in good agreement with those of Hubbell et al. Copyright © 2002 John Wiley & Sons, Ltd.
