electron spectroscopy

[i′lek‚trän spek′träs·kə·pē]
(spectroscopy)
The study of the energy spectra of photoelectrons or Auger electrons emitted from a substance upon bombardment by electromagnetic radiation, electrons, or ions; used to investigate atomic, molecular, or solid-state structure, and in chemical analysis.
