Measurement of the Static Structure Factor for Conduction Electrons with Use of Synchrotron Radiation

Abstract

A technique for directly measuring the static structure factor for electrons with use of synchrotron radiation is described. Results for the conduction electrons in beryllium and the basal plane of graphite show a peak at $k\ensuremath{\cong}2{k}_{\mathrm{F}}$ as predicted, but the pair correlation function shows an anomaly at distances considerably shorter than the mean interparticle separation.
