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.
