Electron interaction in matter: Inelastic collisions
Characteristic X Rays
•
The incoming electron knocks out
an inner shell atomic electron
•
An electron from a higher shell fills
the vacancy and the energy
B emsstrahlung
•
Bremsstrahlung X rays result from
Coulomb interactions between the
incide t e
-
and the nuclei of the
target m terial.
•
The incident e
-
is deflected and
difference is emitted as an X Ray of
an energy characteristic for the
transition
decelerated and loses part of its
kinetic energy in the form of photons
(radiative loss).
