Description

Abstract The program EMI2 computes the liquid-scintillation counting efficiency for pure electron capture, single isomeric and electron capture-gamma nuclides. In this second version, the atomic rearrangement process subsequent to electron capture is described in terms of a more sophisticated KL_1 L_2 L_3 M model of 264 different pathways. The addition of Coster-Kronig transitions improves the accuracy of the method, especially for nuclides of low atomic numbers. A Monte Carlo method is applied to sim... Title of program: EMI2 Catalogue Id: ACPU_v2_0 [ADKR] Nature of problem The standardization of electron capture (EC) nuclides in liquid scintillation detectors is never 100 per cent efficient, depending on several factors such as ionization or chemical quench. A complete description of the EC process is not possible to achieve due to the large number of involved atomic rearrangement pathways. In the first version of the program EMI, an oversimplified KLM model of only 22 pathways was applied. However, a better accuracy in the standardizations, especially for nuclide ...
