Photon-stimulated desorption experiments were performed on the (001) face of LiF for photon energies near the F(2s) and Li(1s) edges (from 37 to 72 eV). There are structures in the F/sup +/ yield above the F(2s) edge which are absent in the Li/sup +/ spectrum, differences in detail in the Li/sup +/ and F/sup +/ yields near the Li(1s) edge, and considerable broadening of the desorption yields as compared to the bulk photoabsorption spectrum. The first observation of a strong x-ray and visible beam-exposure dependence of ion yields from LiF and NaF is also presented. These results are discussed in terms of electronic and defect properties of alkali halides.
