Experiments based on gas thermochromatography were performed with the aim to search for volatile tetraoxide CmO4 in the products of thermal oxidation of microamounts of CmH2–3. The carrier gas was He, and the reagent gas was O2. At their equimolar ratio, the zone of deposition of volatile Cm species at negative temperatures, centered at −80°C, was detected on the quartz column surface. The thermochromatographic peaks formed by plutonium tetraoxide and by the volatile Cm species are similar in… Expand

TLDR
The stability of the "true" oxides AnO4 decreases from Pu to Cm, whereas the isomers with two O2 groups become relatively more stable, and decrease of the An oxidation states along the An series is evident. Expand
