Popis: Photoelectric emission from the valence band, previously measured for CsI, has been investigated in the other alkali iodides and several other halides. As in CsI, the yields rise rapidly from the threshold to values of order 0.1 electron/incident photon. For the iodides, concurrent measurements of reflectivity and optical absorption agree with Martienssen's recent results and show detail consistent with interband transitions. Approximate values for the energy difference between the bottom of the conduction band and the vacuum level are deduced.
