The linear differential scattering coefficients at 60 keV have been measured for UO2(C2H3O2)(2) (.) 2H(2)O (uranyl-acetate) and Th(NO3)(4) (.) 5H(2)O (thorium-nitrate) radioactive compounds at seven angles ranging from 60degrees to 120degrees at intervals 10degrees. The obtained results have been compared with relativistic and non-relativistic theoretical values. (C) 2004 Elsevier Ltd. All rights reserved.
