The Dielectric Formalism for Inelastic Processes in High-Energy Ion-Matter Collisions

In this chapter we analyze the possibilities and ranges of validity of the dielectric formalism to deal with correlated bound electrons in matter by using the shellwise local plasma approximation. This model describes the response of the electrons of the same binding energy as a whole (collectively)...
