Anisotropy of L Sub-Shell X-rays in Tungsten at Photon Energies, below and above the L2-Edge

Abstract

Angular distribution of relative intensities of L X-rays from Tungsten (W) following ionization by photons has been studied at incident photon energies, 10.676 keV (lying between L3 and L2 edges of W) and 17.781 keV. The relative L_λ, L_α and L_β intensities has been observed at both the photon energies that have been found to be comparable. Furthermore, the L_λ X-rays were found to show anisotropy more in comparison to other L x-ray groups at both the energies.
