Auger yields from the decays of 71 Ge, 99m Tc, 111 In and 123−125 I have been calculated using a Monte Carlo model of the Auger cascade that has been developed at the ANU. In addition, progress to improve the input data of the model has been made with the Multiconfiguration Dirac-Hartree-Fock method. Monte Carlo model of Auger cascade Recognising the lack of a consistent theoretical model for the Auger cascade, the August 2011 IAEA special meeting on Intermediate-term Nuclear Data Needs for

A new approach is required, which should use theoretical transition energies and rates suited for the multiply ionized atoms. A model of the Auger cascade, which is based on a Monte Carlo method, has been developed as a first step to address the need. Nuclear structure data is extracted from the Evaluated Nuclear Structure Data File (ENSDF) [29].
