electron energy loss spectroscopy

acronym: EELS
https://doi.org/10.1351/goldbook.08593
Measurement method of vibrational spectroscopy in which a constant-energy beam of electrons passes through or is reflected from a sample and the energy distribution in the transmitted or reflected beam is analysed to give a spectrum of number of electrons against electron energy loss.
Note:
EELS is used for the study of electronic states and has an energy resolution of 0.25 eV or better (corresponding to an approximate wavenumber of 2000 cm−1).
