Any technique in which the sample is bombarded with X-rays and photoelectrons produced
by the sample are detected as a function of energy.
ESCA (Electron
Spectroscopy for Chemical Analysis) refers to the use of this technique to identify elements,
their concentrations, and their chemical state within the sample.
