MICELLE, the micelle size effect on the LS counting efficiency
Description
Abstract This version extends the computation of the liquid-scintillation counting efficiency to electron-capture radionuclides of 30 ≤ Z ≤ 54. The simplified deterministic models of previous versions are replaced by a complete stochastic model, which considers all possible subshells involved in the atomic rearrangement of the atom. The program can simulate samples in the gel phase, including the effects of the micelles on the counting efficiency. These effects have been found to be useful for buildin... Title of program: MICELLE Catalogue Id: ACPU_v3_0 Nature of problem Both Β and electron-capture are decay processes characterized by a large variability in energy. In the first case, one single Β-particle is emitted per decay following the Fermi distribution. In the second, several electrons (Auger and/or Coster-Kronig) of very different energies can be ejected simultaneously. The detailed simulation of these two electron release processes has practical interest in two situations: (1) to standardize radionuclides with a liquid-scintillation counter, (2) to compu ...
