Abstract

A proportional counter spectrometer designed for Investigation of low energy particles has been used for the determination of the K fluorescence yield of argon. X-rays following K capture In iron-55 were used as a source for excitation of the argon atom and the spectrum was measured. The K fluorescence yield was deduced from the comparison of the two peaks shown in the spectrum and corrections were made, taking into account photoelectric absorption in outer shells and reabsorption of secondary X-rays in the counter. The fluorescence yield of argon was found to be 0,087 ± 0,007 •
