Study of the transmission and backscattering of electrons in the energy range 0.5-3 MeV under mulptiple scattering conditions

A knowledge of the motion of electrons in matter is of fundamental importance, particularly in scanning microscopy, in microanalysis and in space physics. We present our experimental results for monoenergetic electrons incident normal to polycrystalline targets under multiple scattering conditions. The measurement gives information concerning the transmission and backscattering coefficients, the angular distributions and the path-length inside the specimen. We give analytic expressions that describe the experimental results accurately over a very wide range of energies (0.05-3 MeV)
