Abstract : Reported values of the K x-ray fluorescence yield of argon lie in two distinct groups, low values (about 7%) and high values (about 13%). A new measurement is reported which gives 14 plus or minus 1.4%. This measurement is made from the escape peak in the pulse-height-distribution of a flow proportional counter with monochromatic x-rays. A Fe-55 radio-isotope was used as the source of primary x-rays. Corrections were made for the L and M ionizations, for the reabsorption of the K fluorescent x-rays, and for background counts.
