High accuracy plutonium mass determination by controlled-potential coulometry

Autor: Nicolas Leguay, Vincent Dalier, Alexandre Ruas, Philippe Moisy, Nicolas Vedel, Romain Sueur

Publikováno v: Radiochimica Acta. 102:691-699

Controlled-potential coulometry is an assay method for determining the quantity of a given element from the measurement of a quantity of electricity. This method has the advantage of not being related to a chemical standard, having an extremely high
