The photoelectric emission from films of LiF and KCl and sheet Ni due to extreme ultraviolet radiation of 8 photon energies from 10 to 50 ev was studied with a planarpotential retarding analyzer. Current-voltage diagrams which provide an analysis of the normal energy of the emitted electrons were obtained. Photons of energies greater than twice the depth of the filled band below vacuum potential produce an effect which may be interpreted as two-electron emission. The results suggest this is an Auger process rather than being due to strong electron scattering. The results also indicate that the emission from LiF and KCl is preferentially in the forward direction. (auth)
