The meeting participants reviewed the current measurement programmes, continued with the review of proposed transactinium isotope decay data, and recommended the release of a list of proposed half-life values which will be subject to revision based on comments received. The second meeting of the participants in the IAEA coordinated research programme to measure and evaluate required nuclear decay data of transactinium isotopes, was convened by the IAEA Nuclear Data Section on 30 April - in Aix-en-Provence, France. International Nuclear Information System (INIS) Second coordinated research meeting on the measurement and evaluation of transactinium isotope nuclear data, Aix-en-Provence, 30 April. 6600 years BP) whose 14C age agrees with previous determination and which shows no sign of A sequential leaching was applied to a young carbonate sample (ca. The main advantage is that all of steps leaching and hydrolysis are performed in the same vial for a particular sample. Coupling the automated hydrolysis system to the gas ion source of AixMICADAS, enables us to develop a method involving sequential leaching of carbonate samples with direct 14C measurements of the leached fractions and the residual sample. These tests show that samples ranging between 10 and 100 μg C can produce a 12C- ion beam of the order of 10-15 Î❊ during time spans ranging from 3 to 30 min depending on the sample mass. The performances of the gas ion source and its gas interface system were tested with two CO2 production units: the elemental analyzer and the automated carbonate hydrolysis unit. AixMICADAS is thus limited solely by the 14C contamination of samples in the field and in the laboratory. Direct measurements of geological graphites indicate a machine background equivalent to an age of 68,000 years BP. Measurements of IAEA reference materials of various 14C ages show a good agreement with consensus values. The analyses performed during the first half-year of operation show that a precision of about 2‰ is reached on modern samples of about 1 mg of carbon. It is coupled to a versatile gas interface system that ensures stable gas measurements from different sources: a cracker for CO2 in glass ampoules, an elemental analyzer for combusting organic matter and an automated system to handle carbonate by wet chemistry. The hybrid ion source works with graphite targets and CO2 gas. ![]() AixMICADAS operates at around 200 kV with carbon ion stripping in helium leading to a transmission of about 47%.
