Quantum-yield and photoelectron-energy distribution measurements on evaporated LaF/sub 3/ films have been made in the photon energy range 10 to 27 eV. Photoemission from the F/sup -/2p 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. 3 figures.
