Electron interaction with matter
•
Same mass of the atomic e- to
which they transfer energy in
collisional events
•
Multiple elastic collisions of a
high-energy e
-
(multiple
scattering)
produce multiple
small angle deflections
•
The e
-
follows a zigzag path (it can
also be back-scattered) while it
continuously loses kinetic energy
through inelastic collisions with
atoms until its kinetic energy is
gone
