Abstract

Building on the relationship between the mixed dynamic form factor (MDFF) for inelastic electron scattering and the one-particle density matrices of the initial and final states of the scatterer it is shown that the MDFF contains information both on the spatial density and the spatial coherence of excitations.

We discuss how the MDFF can??at least partly??be measured in scattering geometries invoking channeling conditions. Therefrom, the localization of inelastic events can be determined.
