We have extended our previous microscopic numerical calculations for the dynamic structure factor of the electron gas at large momentum transfers to include the overall relaxation of the central peak due to electron-hole correlations and self-energies. These contributions vary slowly with energy transfer as had been anticipated. We confirm our excellent agreement with the multiple peaks experimentally observed in Li. Satisfaction of the sum rules is built into the formalism, and we confirm this numerically.

Abstract

We have extended our previous microscopic numerical calculations for the dynamic structure factor of the electron gas at large momentum transfers to include the overall relaxation of the central peak due to electron-hole correlations and self-energies. These contributions vary slowly with energy transfer as had been anticipated. We confirm our excellent agreement with the multiple peaks experimentally observed in Li. Satisfaction of the sum rules is built into the formalism, and we confirm this numerically.
