A procedure for the automated determination of isotopic abundances of silicon from biogenic and lithogenic particulate matter and from dissolved silicon in fresh or saltwaters is reported. Samples are purified using proven procedures through the reaction of Si with acidified ammonium molybdate, followed by precipitation with triethylamine and ...

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1970
1. The method of isotopic dilution was used to determine trace amounts of a heavy alkali metalcesium. 2. A new variation of the method of isotopic dilution using a radioactive isotope without a carrier was proposed. 3. It was established experimentally that the system magnesium dipicrylaminate — nitrobenzene can be used for ...

Possible candidates for multiple chiral doublet bands in cesium isotopes
Physical Review C, 2018Following the reports of candidate chiral doublet bands observed in odd-$A$ cesium isotopes, the triaxial deformations with corresponding configuration and the possible multiple chiral doublet ($\mathrm{M}\ensuremath{\chi}\mathrm{D}$) phenomenon in $^{125,127,129,131}\mathrm{Cs}$ are investigated within the adiabatic and configuration-fixed constrained

Distribution of Cesium Isotopes in UO2 Reactor Fuel
The absolute abundances of several isotopes of cesium and uranium in an enriched uranium oxide fuel rod have been measured with a mass spectrometer, using the isotope dilution technique. Samples taken from the inside and edge of the rod have shorn that the cesium abundances, particularly Cs134, near the centre are much less than expected, whereas at ...openaire +1 more source
