Özet

L X-ray differential cross-sections of uranium were calculated at several polar scattering angles (85 degrees, 95 degrees, 105 degrees, 115 degrees, 125 degrees, and 135 degrees) at 59.54-keV photon energy by using a Si(Li) detector. We observed that L-l and L alpha X-rays were dependent on the polar scattering angle, whereasL(beta) and L-gamma X-rays were independent of the polar scattering angle. Therefore, the anisotropy parameters for L-l and L-alpha X-rays were obtained using the intensity ratios of L-l to L-gamma X-rays and of L-alpha to L-gamma X-rays to reduce some systematic errors.
