Impact parameters and intraband scattering in electron diffraction from thin foils

Abstract

In transmission electron microscopy, Al core losses excited by currents localized about atomic cores show fringes similar to the thickness fringes observed in zero loss, The fringes observed in the inelastically scattered electrons result from intraband scattering in the dispersion of Bloch waves even when the losses are over 1 kV. The analysis uses dynamical scattering with inelastic scattering. The impact parameter method is used to determine transition rates from electron currents distributed across the unit cell of the crystal.
