Summary of existing information on the incoherent scattering of photons, particularly on the validity of the use of the incoherent scattering function

The Evaluated Photon Data Library, 1997 version (EPDL97), is designed for use in photon transport calculations at Lawrence Livermore National Laboratory. This library includes photon interaction data for all elements with atomic number between Z = 1 (hydrogen) and 100 (fermium), including: photoionization, photoexcitation, coherent and incoherent scattering, and pair and triplet production cross sections. For use in applications data is provided for all elements over the energy range 1 eV to 100 GeV. This report documents the sources and treatment of the data included in this library. EPDL97 completely supersedes the earlier 1989 version of EPDL and it is highly recommended that users only use the most recent version of this library.

“…Since we expect the best performance of the new experimental method for photons of low incident energies ð11230 keVÞ, we believe that it would be very suitable for Compton scattering experiments at small photon momentum transfer. This region is of special interest for investigations of the incoherent scattering function (see Hubbell, 1997). For that task, a specially designed variant of the presented experimental setup for a measurement at forward scattering angle would be of particular interest.…”

“…Recent second-order S-matrix relativistic calculations raise the question regarding the limitations of validity (Suric´et al, 1991) the user-friendly and widely available data based on the approximations, like the impulse approximation (IA) or incoherent scattering function (Hubbell, 1997). Therefore, improved measurements of Compton scattering are still required.…”

Combining Monte Carlo methods with coherent wave optics for the simulation of phase-sensitive X-ray imaging

Phase-sensitive X-ray imaging shows a high sensitivity towards electron density variations, making it well suited for imaging of soft tissue matter. However, there are still open questions about the details of the image formation process. Here, a framework for numerical simulations of phase-sensitive X-ray imaging is presented, which takes both particle-and wave-like properties of X-rays into consideration. A split approach is presented where we combine a Monte Carlo method (MC) based sample part with a wave optics simulation based propagation part, leading to a framework that takes both particle-and wavelike properties into account. The framework can be adapted to different phasesensitive imaging methods and has been validated through comparisons with experiments for grating interferometry and propagation-based imaging. The validation of the framework shows that the combination of wave optics and MC has been successfully implemented and yields good agreement between measurements and simulations. This demonstrates that the physical processes relevant for developing a deeper understanding of scattering in the context of phase-sensitive imaging are modelled in a sufficiently accurate manner. The framework can be used for the simulation of phase-sensitive X-ray imaging, for instance for the simulation of grating interferometry or propagation-based imaging.
