EELS Signal/Intensity Dependence on Z-(Atomic) Number

- An Online Book -  

This book (Practical Electron Microscopy and Database) is a reference for TEM and SEM students, operators, engineers, technicians, managers, and researchers.


The chemical elements with atomic (Z-) numbers smaller than 33 generate very large EELS signals, while the other elements generate smaller signals.

Pearson et al. [1] experimentally and theoretically (based on one-electron Hartree-Slater calculations) found that the intensities of L2,3 white lines for most of the 3d and 4d transition metals decreased nearly linearly with increasing atomic number, reflecting the filling of the d states.
