Many-Electron Effects in the Shape of theCl Kα1,2X-Ray Emission Lines

Abstract
Fluorescent Cl Kα x-ray spectra were observed with a double-crystal spectrometer. Kα line shapes appeared asymmetrically smeared by the presence of the shakeoff satellites within the natural width of main lines. Bonding effects of KMnLMn satellites—parasites—of chlorine were observed (n=1,2) for the first time. The relative intensities of parasites were measured in a number of chlorine compounds. Except for RbCl and CsCl, the relative intensities were found to be related to the covalency of the compounds.
