Abstract : Several experimental techniques for determining electron attenuation lengths in metals in the energy range up to 100 keV are discussed. Each technique is seen to contribute data to specific regions of this spectrum, although there is a serious lack of information between 10 eV to 1 keV. In general, electron beam experiments and thin film structures are confined to specific regions in energy due to practical limitations. Vacuum photoemission does not have this limitation, although it too, has provided little data in the region of the gap between 10 eV and 1 keV. For a few materials, some data does exist and some comparisons with theory are possible. (Author)
