The document discusses Auger electron energy and Auger electron spectroscopy. It explains that Auger electron energy is dependent on atomic energy levels and not the primary beam energy. It also describes modifying the formula for calculating Auger electron energy by accounting for the spectrometer work function to get a value comparable to measured energies. Finally, it notes that Auger electron spectroscopy is used for surface analysis since emitted electrons typically have energies between 50 eV to 3 keV, giving it surface sensitivity.

1. Auger electron energy is independent of the primary beam
energy and is dependent only on the atomic energy levels.
Auger transition (KL1L3) energy for Al, for example, may
be calculated as follows:
But measured energy value is 1354eV. Here there is a
difference between these value so we made a correction in
the formula.

2. Formula is modified by taking into account the
spectrometer work function Hence, the kinetic energy
of the ABC Auger electron may be approximated as
follows:
In the above expression, ФA is the work function of
the analyzer. we use this formula and we get the
energy value is comparable to the measured value

3. Applications
 Auger electron spectroscopy
Auger electron spectroscopy is based on Auger effect
and this is also invented by Pierre Auger.
It is mainly use in surface analysis so it surface
sensitive. Surface sensitivity in this spectroscopy arises
from that emitted electrons usually have energies
ranging from 50 eV to 3 keV
