Resumen:
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), screening the interaction with
the impinging ion. It considers separately each sub-shell of target electrons, with the
corresponding dielectric response. The density of electrons and the energy gap are
included explicitly by employing the Levine and Louie dielectric function. The goal
of this chapter is to summarize and review the capability of this model to deal with
fundamental magnitudes of the atomic collisions expressed as different moments of
the energy loss: ionization cross sections (single or multiple, differential, and total),
stopping power (and mean excitation energy), and energy loss straggling. This review
covers a wide range of the collisions of ions with gases and solids, paying special
attention to multi-electronic targets. The advantages and disadvantages of the model
in comparison with independent electron ones, ranges of validity and future prospect
will be considered.
