Measurement of relative L X-ray intensity ratio following radioactive decay and photoionizationYalçin, P.Porikli, S.Kurucu, Y.Şahin, Y.Intensity ratio by photoionizationIntensity ratio following radioactive decayL X-ray intensity ratioL X-raysRadioisotopesThe measurements of the L X-ray intensity ratio I (L α) / I (L β), I (L α) / I (L γ), I (L α) / I (L ι), I (L β) / I (L γ) and I (L ι) / I (L γ) for elements Dy, Ho, Yb, W, Hg, Tl and Pb were experimentally determined both by photon excitation, in which 59.5 keV γ-rays from a filtered radioisotope 241Am was used, and by the radioactive decay of 160Tb, 160Er, 173Lu, 182Re, 201Tl, 203Pb and 207Bi. 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 α / L β), I (L α / L γ), I (L α / L ι), I (L β / L γ) and I (L ι / L γ) 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. © 2008 Elsevier B.V.
