Dynamical scattering effects in electron scattering measurements of the Compton profiles of solids

In electron scattering measurements of the Compton profiles of solids, multiple scattering events contribute strongly to the observed profile. The dominant contribution to the multiple scattering arises from events in which Bragg scattering is followed by Compton scattering. The Bragg scattering is calculated by using a multi-slice approach that allows for dynamical scattering, and each Bragg beam is then treated as a source of Compton scattering. In this paper, the dependence of multiple scattering on the energy of the incident beam and on the thickness, orientation, crystal structure and atomic number of the sample are investigated to determine the paramenters that affect the multiple scattering most strongly, and to seek ways in which multiple scattering can be reduced in experimental work.
