The angular dependence of L-3-subshell to M-shell vacancy transfer probabilities for the elements Lu, Hf, Ta, W, Os and Pt have been measured at the excitation energies of 5.96 keV and K X-rays of Zn, Ga, Ge, and As, respectively, at seven angles varying from 120degrees to 150degrees. Energies of K X-rays are above the L-3 edge but below L-2 edge energies of the respective target elements under reference; therefore, the M X-rays are produced not only due to direct interaction of incident photons with NI-shell electron but also due to the decay of L-3-subshell vacancies to M-shell. Because the angular dependence from L-3-subshell to M-shell vacancy transfer probabilities is not found in the literature, to the best of our knowledge there are no experimental values for worked elements. Therefore, the results for the elements obtained in the present study constitute the first experimental measurements and no comparison was made with other experimental and theoretical results. It has been observed that angular dependence from L-3-subshell to M-shell vacancy transfer probabilities increases with increasing cos theta. (C) 2004 Elsevier Ltd. All rights reserved.
