Abstract
A microscopic calculation for the electron gas which is parameter free and satisfies the sum rules predicts twin peaks in the dynamic structure factor which are in substantial quantitative agreement with reported measurements on Be and Al. The twin peaks are generated by dynamic Coulomb correlations between pairs of electrons. No evidence is seen of a corresponding maximum in the pair correlation function.Keywords
