The 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 57.142keV. The measurements, in the region from 36.847 to 57.142keV, were done in a transmission geometry utilizing the Kα2, Kα1, Kβ1 and Kβ2 X-rays from different secondary source targets excited by the 59.54keV 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. •The effective atomic numbers and electron densities determined for some samarium compounds from total mass attenuation coefficients near the K edge.•The measurements performed using secondary excitation geometry and a Si(Li) detector.•The experimental results compared with the theoretical calculation.
