 Title    Photoelectron Spectroscopy of the Alkali Metals Rb and Cs and their Metal Rich Oxides  
 Abstract    The alkali metals Rb and Cs and their suboxides CS11O3, CS7O (= [Csn03]Csio) and [Csn03]Rb7 have been investigated by UPS (Hei). Extremely narrow 02p levels are observed, as well as significant differences in the binding energies of the 5p levels of chemically different Cs-atoms. From energy loss structures (surface plasmons) electron concentrations are determined. The residts arc discussed in terms of structurally derived bonding models. The alkali metal suboxides are of importance in IR-sensitive Ag/Cs/O-photocathodes.

 Title    Crystallisation Processes in Metal Rich Rubidium Oxides  
 Abstract    On the basis of X-ray investigations a structural model for the orientational disorder of Rbg02 clusters in the rubidium suboxide RbeO is derived, which is in accordance with details of the thermal analysis of the ordering process. In the second part the thermal and structural investigations of a metastable phase of the probable composition Rbe,330 are described. The phase is formed by warming quenched samples Rb;rO (9 >x > 7) to co. 140 K and decomposes at ca. 183 K. Its cubic structure bears relationships to the structure of rubidium as well as to YBe6 (replacing B12 icosahedra in the latter compound by Rb atoms). A special DTA instrument used for the investigation of Rbe.330 is described.
