摘要：

Plasmon damping in the three-dimensional homogeneous electron gas is investigated within the formalism of second-order perturbation theory, concentrating on the effects of static and dynamic screening. We have found several different theoretical approaches leading to comparable results, especially in the metallic-density regime. Using a spin-dependent interaction, however, significantly improves the results of our theory towards a better agreement with the experiments.
