THE INFLUENCE OF MULTIPLE SCATTERING ON THE MEASUREMENT OF THE CIRCULAR POLARIZATION OF $gamma$-RAYS

Journal Article · · Nucl. Instr. Methods

The circular polarization of gamma rays is usually measured by Compton forward scattering from comparatively thick (about 1 cm) magnetized iron cylinders. Therefore, multiple scattering was determined by measuring the counting rate as a function of the iron thickness and was indeed found large (up to 35%). Nevertheless, it was shown that multiple scattering decreases the polarization efficiency by only a few percent for the photon energy range between 600 and 1220 kev. (auth)
