Surface plasmon resonance
In EELS, you can have a surface plasmon resonance from any electrons that can be excited by the incident electron beam from deeper shells; they do not have to take part in electrical conductivity in absence of excitation. This is similar to bulk plasmon resonances, which are seen in EELS for nearly any dielectric (there is one, maybe two exceptions). Please let me know if I missed something. Regards.
