Title: Nonlinear stopping power and energy-loss straggling of an interacting electron gas for slow ions

Abstract

Theoretical calculations of the basic quantities that characterize thestopping of an interacting electron gas for slow ions are presented. Anappropriate low-frequency expansion for the imaginary part of the densityresponse function has been used to modify well-known results for thenoninteracting electron gas. The inner dissipative nature of the elementaryelectron-hole excitation is characterized by a complex local-field correctionfunction. The basic quantities are expressed in terms of the phase shiftsdetermined from a nonlinear density-functional formalism.
