Abstract
Electron momentum spectroscopy is a tool ideally suited for the study of energy-resolved momentum densities. Here we present new data from a high-energy EMS experiment using 50 keV incoming and 25 keV outgoing electrons. Both the measured energy distributions and the measured momentum distributions are affected by multiple scattering. However, after correcting for these effects, neither distribution can be fully understood using electronic structure calculations that take electron-electron correlation into account only on a mean-field level.
