Abstract
A study has been made of the wake of a swift charged particle in an electron gas using the full random-phase-approximation dielectric function of this medium. Our earliest work using the plasmon-pole approximation to the dielectric function gives a good account of most aspects of the wake when the velocity of the particle is greater than the Fermi velocity.Keywords
