Calculations are reported using the multiple scattering, Green function method for the transmission electron energy-loss near-edge structure (ELNES) of inner shell excitations. These reveal a high degree of sensitivity to the local crystallographic environment. A plot of the reciprocal of the ejected crystal electron wavevector for a particular feature in the ELNES against nearest-neighbor distance is found to be linear over a small range. This suggests a method for the quantitative measurement of local strain using ELNES obtained with a subnanometer electron probe. An experimental K-edge spectrum from beryllium is used to demonstrate the removal of plasmon multiple inelastic scattering artifact from ELNES by the method of logarithmic deconvolution, without adjustable parameters.
