Abstract

Quantum-yield and photoelectron-energy-distribution measurements on evaporated LaF3 films have been made in the photon energy range 10–27 eV. Photoemission from the F2p valence band indicates a bandwidth of 3.5 ± 0.3 eV and a photoelectric threshold of 11.7 ± 0.3 eV. The photoelectron spectra exhibit features that can be identified as density-of-states structures of the valence and conduction bands. An attempt is made to relate these structures to the initial and final states of ultraviolet transitions.
