Abstract

Experimental determination of L fluorescence cross-sections for elements with 45<Z<50 have been determined at 9keV using Synchrotron radiation. This work is part of an investigation we did at low energies in the same group of elements. The individual L X-ray photons, Ll, L?, L? I, L? II, L? I and L? II produced in the target were measured using a Si(Li) detector. The experimental set-up provided a low background by using linearly polarized monoenergetic photon beam, improving the signal-to-noise ratio. The experimental cross sections obtained in this work were compared with data calculated using coefficients from Scofield (1973), Krause et al., (1978), Krause (1979) and Scofield and Puri et al. (1993, 1995). © 2011 Elsevier Ltd.
