=================================================================================

Hydrogenic model and Hartree-Slater model give good results for evaluating the K-shell excitation cross-section. A comparison of K-edge and cross-section profiles for low atomic number (Z) elements [1] shows that the cross-section profiles present the K-edge roughly for an edge where the fine structures are important, e.g. for boron nitride (BN).

The ratio between different elements in a TEM specimen can be determined using Hartree-Slater cross sections in EELS.
