Abstract
THE part which strontium oxide plays in the functioning of the oxide cathode is not well understood ; a suitable model of the combined barium and strontium oxides on the band theory is still not satisfactory. Further, lack of sufficient observations in the soft X-ray region over the operating temperature-range prevents a fuller knowledge of how the valence band densities are related in the solid solution of the oxides. It is, of course, possible to go some way towards understanding the oxide cathode if the main and relevant properties of each component can be studied.
