We present and discuss here the possibilities and ranges of validity of the shellwise local plasma approximation to deal with the inelastic collisions. This model describes the response of target bound electrons collectively by means of the dielectric formalism, considering the different subshells and binding energies. We present here our results for ionization cross sections, energy loss of ions in matter and also energy los straggling. A wide spectrum of collisions of ions with gases and solids, atomic or molecular targets is covered, with. special attention to multielectronic relativistic targets.
