Abstract

Ll, Lalpha, Lbeta and Lgamma X-ray differential cross-sections, fluorescence cross-sections and L-i-subshell (sigma(L1), sigma(L2), and sigma(L3)) fluorescence cross-sections were measured for Er, Ta, W, Au, Hg and Tl at an excitation energy of 59.6 keV using a Si(Li) detector. The differential cross-sections for these elements have been measured at different angles varying from 54degrees to 153degrees at intervals of 9degrees. The Ll and Lalpha groups in the L X-ray lines are found to be spatially anisotropic, while those in the Lbeta and Lgamma peaks are isotropic. Experimental and theoretical values of L X-ray fluorescence cross-sections and L-i-subshell X-ray fluorescence cross-sections were compared. (C) 2003 Elsevier Science Ltd. All rights reserved.
