Measurement of relative L X-ray intensity ratio following radioactive decay and photoionization
Özet
The measurements of the L X-ray intensity ratio I(L alpha)/I(L beta), I(L alpha)/I(L gamma), I(L alpha)/I(L iota), I(L beta)/I(L gamma) and I(L iota)/I(L gamma) for elements Dy, Ho, Yb, W, Hg, Tl and Pb were experimentally determined both by photon excitation, in which 59.5 keV gamma-rays from a filtered radioisotope Am-141 was used, and by the radioactive decay of Th-160, Er-160, Lu-173, Re-182, Tl-201, Pb-203 and Bi-207. L X-rays emitted by samples were counted by a Si(Li) detector with resolution 160 eV at 5.9 keV. Obtained values were compared with the calculated theoretical values. Theoretical values of the I(L alpha/L beta), I(L alpha/L gamma), I(L alpha/L iota), I(L iota/L gamma) and I(L iota/L gamma) intensity ratios were calculated using theoretically tabulated values of subshell photoionization cross-section, fluorescence yield, fractional X-ray emission rates, Coster-Kronig transition probabilities. It was observed that present values agree with previous theoretical and other available experimental results. (C) 2008 Elsevier B.V. All rights reserved.
