Abstract
Considerable structure has been observed at the intrinsic optical absorption edge of annealed films of BaO, BaS, BaSe, BaTe, SrO, SrS, SrSe, and SrTe at -160°C. Photoemission measurements allow an estimate to be made of the energy separation between the top of the valence band and the vacuum level.
