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. Author
