DURAK, RIDVAN/0000-0002-3935-176X; Durak, Ridvan/0000-0002-3935-176X; Akman, Ferdi/0000-0002-8838-1762WOS: 000355889000016PubMed: 25880612The effective atomic numbers and electron densities of some samarium compounds were determined using the experimental total mass attenuation coefficient values near the K edge in the X-ray energy range from 36.847 up to 57.142 keV. The measurements, in the region from 36.847 to 57.142 keV, were done in a transmission geometry utilizing the K alpha(2), K alpha(1), K beta(1) and K beta(2) X-rays from different secondary source targets excited by the 59.54 keV gamma-photons from an Am-241 annular source. This paper presents the first measurement of the effective atomic numbers and electron densities for some samarium compounds near the K edge. The results of the study showed that the measured values were in good agreement with the theoretically calculated ones. (C) 2015 Elsevier Ltd.
