Özet

The measurements of the K X-ray intensity ratio I(K alpha(2)/K alpha(1)), I(K beta(1)/K alpha(1)) and I(K beta/K alpha) for elements V, Mn, Zn, Tc, Ru, Cd, Xe, Ba, Cs, Hg and Rn were experimentally determined both by photon excitation in which 59.5 keV gamma-rays from a Am-241 and 123.6 keV gamma-rays from a Co-60 were used, and following the radioactive decay of Cr-51, Fe-55, Ga-67, Tc-99, In-111, I-131, Ba-133, Xe-133, Cs-137, Tl-201 and Ra-226. K 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 theoretical values. It was observed that present values agree with the previous theoretical and other experimental results. (c) 2006 Elsevier B.V. All rights reserved.

The measurements of the K X-ray intensity ratio I(Ka2/Ka1), I(Kb1/Ka1) and I(Kb/Ka) for elements V, Mn, Zn, Tc, Ru, Cd, Xe, Ba, Cs, Hg and Rn were experimentally determined both by photon excitation, in which 59.5 keV c-rays from a 241Am and 123.6 keV c-rays from a 60Co were used, and following the radioactive decay of 51Cr, 55Fe, 67Ga, 99Tc, 111In, 131I, 133Ba, 133Xe, 137Cs, 201Tl and 226Ra. K 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 theoretical values. It was observed that present values agree with the previous theoretical and other experimental results.
