Plasmon decay mechanisms in electron-aluminum collisions

A projectile traveling inside a metal can excite bulk plasmons (collective oscillations of the electron gas) that eventually decay. The two main decay mechanisms are the excitation of a Bloch electron and the excitation of a pair of interacting free electrons. In recent publications we developed a m...

Sumario:A projectile traveling inside a metal can excite bulk plasmons (collective oscillations of the electron gas) that eventually decay. The two main decay mechanisms are the excitation of a Bloch electron and the excitation of a pair of interacting free electrons. In recent publications we developed a model to study these mechanisms for proton impact. In this Brief Report, we extend that model in order to consider an electron as the projectile and deal with the numerical difficulties this projectile choice brings along. © 2005 The American Physical Society.
