Popis:	A many-body perturbation-theoretic calculation of the double-plasmon excitation in an electron gas is presented, using Feynman diagrams. The low-q limit of the inverse mean free path for this second order process is evaluated in the random-phase-approximation, and it is compared to previous theoretical and experimental estimations.
