Determination of K shell absorption parameters for some lanthanides using the X-ray attenuation method

Durak, Ridvan/0000-0002-3935-176X; DURAK, RIDVAN/0000-0002-3935-176X; Akman, Ferdi/0000-0002-8838-1762WOS: 000367613700014The total attenuation cross section at the K edge, absorption jump ratio, jump factor, Davisson-Kirchner ratio, and oscillator strength parameters for the K shell were determined by measuring the total attenuation cross sections around the K edge for Pr, Nd2O3, and Sm. The measurements were performed in a secondary excitation geometry using the K alpha(2), K alpha(1), K beta(1), and K beta(2) X-rays (in the region from 31.817 to 55.293 keV) from different secondary source targets excited by the 59.54 keV gamma-photons from an Am-241 annular source. It is the first time that the Davisson-Kirchner ratio values have been determined for present samples. The experimental results were compared with the theoretically calculated and other available experimental results.Ataturk UniversityAtaturk University [2011/82]This work was done with the support of the Ataturk University Research Fund under project No. 2011/82

Determination of L X-ray fluorescence parameters for Ho, Lu, W, Hg and Bi

In this work, L X-ray fluorescence cross sections, L sub-shell fluorescence yields and level widths and radiative vacancy transfer probabilities of L sub-shells to Mi, Ni and Oi sub-shells were measured for the elements Ho, Lu, W, Hg and Bi. Energy dispersive X-ray fluorescence (EDXRF) technique was used to measure L X-ray photons. To obtain related parameters, we used 59.54keV gamma photons of 241Am radioactive point source. Emitted L X-ray photons from targets were collected by means of a Si(Li) detector with resolution of 180eV at 5.9keV. The present results are generally in a good agreement with theoretical calculations and the other results obtained in the literature, within their range considering experimental uncertainty

The measurements were performed using photons of 59.54 keV emitted from an Am-241 (about 100 mCi) point source and a high resolution Si(Li) detector. The experimental results were compared with theoretical calculations and the other results obtained from literature

Updated Database for K-Shell Fluorescence Yields

2nd International Conference on Advances in Natural and Applied Sciences (ICANAS) -- APR 18-21, 2017 -- Antalya, TURKEYDURAK, RIDVAN/0000-0002-3935-176X; Akman, Ferdi/0000-0002-8838-1762WOS: 000405093100090This study presents a summary of experimental data of K-shell fluorescence yields (omega(K)) published in the period of time between 2010 to february-2017. The fluorescence yields (omega(K)) of elements in the range 23 <= Z <= 60 taken directly from different sources were reviewed and presented in a table form. Finally, the experimental and empirical values in the literature have been reported and commented.Agri Ibrahim Cecen Univ, IC Fd
