The dissociation energies and ionization potentials of gaseous oxides in the Th-O, Zr-O, Ti-O, Eu-O, and U-O systems have been determined by high temperature mass spectrometry. Dissociation energies were derived from gaseous equilibrium measurements, while the ionization potentials were obtained from electron impact threshold measurements. Specifically, data were obtained for gaseous ThO, ThO2, ZrO, ZrO2, TiO, TiO2, EuO, UO2, and UO3. Attempts to characterize the higher oxide of aluminum, AlO2, were unsuccessful. New experimental information on the ionization potentials of Th, Zr, and Eu was also obtained. The results make it possible to accurately define the energetics of a number of ion-neutral and neutral-neutral reactions of the metals which are of importance in the analysis of nuclear burst effects.
