Collisions and Stopping of Fast Charged Particles in Matter
Francesc Salvat
This text is intended to offer a consistent presentation of the theory of collisions and stopping of charged particles in matter, limited to the range of intermediate kinetic energ…

Inelastic collisions of fast charged particles with atoms. Relativistic plane-wave Born approximation
Francesc Salvat
A detailed formulation of the relativistic plane-wave Born approximation for inelastic collisions of charged particles with free atoms and positive ions is presented. The wave func…

Causality and dielectric functions for linear media with spatial dispersion
Josep Llosa, Francesc Salvat
We extend Kramers-Kronig relations beyond the optical approximation to dielectric functions that depend not only on frequency but on the wave number as well. This implies extending…
