After an inner
shell excitation an atom has an energy above its ground
state. It can relax and lose some of this energy in
several ways, of which two are described here. Both start
with an outer electron jumping in to fill the vacancy in
the inner shell.
X-ray emission. Energy is given off as a single X-ray
electron emission. Energy is given off by one of the
outer electrons leaving. It carries a characteristic kinetic
These two alternative processes are simulated opposite.
Following a K shell excitation, why are the energies of
the emitted characteristic X-ray and the equivalent emitted
Auger electron slightly different?
