Resonance Potentials in Thin Films of Potassium Chloride

Low-Energy Electron Transmission through Thin-Film Molecular and Biomolecular Solids

“…From comparisons with optical absorption experiments, it has been found that exciton levels existed near maxima in the transmitted current. More systematic investigations were later performed by Jacobs et al, Fredrikov and Goryacheva, and Fredericks and Cook, who interpreted structure in their spectra as electron interaction with crystal imperfections. In the 1970s, LEET experiments in pure , and doped alkali halide films, as well as alkaline earth fluoride films, were performed by Hamill and co-workers.…”
