K -Shell Auger Transition Rates and Fluorescence Yields for Elements Ar-Xe

We use calculated Auger and radiative transition rates to compute K-shell fluorescence yields for 18≤Z≤54. The calculated fluorescence yields are generally higher than the most recent measurements (by as much as 8%). In addition we compare the calculated Auger rates with measured KLL and KLM intensities, the calculated KLL total yield with other calculations, and the calculated KLX/KLL and KXY/KLL ratios with measurements.
