摘要：

By using an effective independent-particle model for an interacting electron gas, the relaxation rate of excited electrons close enough to the Fermi surface is calculated. The theoretical description is based on a binary collision treatment, implemented by an approximate nonlinear characterization of the residual screened interactions and exact phase-shift calculations. The important constituents of a consistent attempt are discussed. The results obtained are analyzed and compared to those based on perturbative Linear-screening predictions. Reductions in the lifetime of excited electrons are found. Comparisons with experimental data from different sources are made.
