Calculation of emission probabilities of X-rays and Auger electrons emitted in radioactive disintegration processes

A complete set of data for the decay scheme of a radionuclide requires know ledge of the emission probabilities of X-rays and Auger electrons. If adopt ed sets of transition probabilities for the transitions of the decay scheme and atomic shell data (such as fluorescence yields and relative emission p robabilities) are available, the emission probabilities of the X-rays and A uger electrons can be calculated from these data. Only data calculated in t his way are consistent with the adopted input data and can be compared with measured data. Conclusions can be drawn with respect to the internal consi stency of the data sets by comparing the measured and calculated data. Henc e, the EMISSION program has been developed and tested to calculate X-ray an d Auger electron emission probabilities along with their error propagation. (C) 2000 Elsevier Science Ltd.
