%X Electron momentum spectroscopy (EMS), based on kinematically complete observations of high energy electron impact ionisation events, directly observes energy&#150;momentum dispersion laws and densities of electrons in solids. The valence electronic structure in the near surface region, up to a depth of about 20 &#197; is probed for thin free-standing films (about 100 &#197;) by the multiparameter EMS spectrometer at Flinders University. The principles of the measurement are described and its application to the determination of energy&#150;momentum densities in a range of amorphous, polycrystalline and crystalline materials is discussed.
