"Coherence in electron energy loss spectrometry";
Journal of Electron Spectroscopy and Related Phenomena, 143 (2005), S. 81 - 95.



Kurzfassung englisch:
Coherence effects in electron energy loss spectrometry (EELS) and in energy filtering are largely neglected although they occur frequently
due to Bragg scattering in crystals.We discuss how coherence in the inelastically scattered wave field can be described by the mixed dynamic
form factor (MDFF), and how it relates to the density matrix of the scattered electrons. Among the many aspects of "inelastic coherence"
are filtered high-resolution images, dipole-forbidden transitions, coherence in plasma excitations, errors in chemical microanalysis, coherent
double plasmons, and circular dichroism.
