Abstract
Electron momentum spectroscopy is a tool ideally suited for the study of th e energy-resolved momentum densities. Here we present new data from a high- energy EMS experiment using 50 keV incoming and 25 keV outgoing electrons. Momentum profiles have been measured from a thin aluminum film for the 2p c ore level and the valence band near E,. The resolution of these momentum pr ofiles, as well as the effects of multiple scattering are discussed. It is found that the high-energy EMS experiment measures momentum densities with superior resolution and very little background. (C) 2001 Elsevier Science B .V. All rights reserved.
