EFFECTIVE ANALYSIS DEPTH

Effective analysis depth

in IS characterizes the layer of substance where the primary electron excites the core level and experiences elastic reflection at a large angle (necessary to leave the solid in the reflection geometry). The value of

depends of experiment geometry and mean free path of the electron with initial energy Ep and the energy Ep-

after core level excitation.
The effective analysis depth is determined by the expression:
