K-Series Fluorescence Yields of Argon, Copper-65, and Indium-113

Abstract

$K$-series fluorescence yield measurements have been made for A, ${\mathrm{Cu}}^{65}$, and ${\mathrm{In}}^{113}$ with a proportional counter spectrometer and found to be 0.081±0.006, 0.39±0.02, and 0.82±0.02, respectively. The method is discussed and a comparison with theoretical values is noted.
