The purpose of this work is to investigate and quantify x-ray fluorescence, its production spectroscopy. Characteristic with different energies was obtained from six various elements using Am-241 source 59.5 keV. It found that energy intensity increase increasing atomic number material. X-ray spectroscopy studied for such in respect their Kα proportional counter. Furthermore, fluorescence produ...

Abstract We detail the design of a variable energy, x-ray fluorescence source using low activity (1.8×10 6 dpm) 99 Tc β that irradiates thin foils. By rotating among foils Ti, Zn, Nb, Ag, and Au, device produces x rays between 4 70 keV at rate near 1 Hz. When is placed in storage position, external radiation non-detectable. The shielding rotation mechanism permits use vacuum liquid nitrogen tem...

Strong characteristic Kα X-ray lines are accompanied by weak lines due to the radiative Auger effect (RAE) [1, 2]. The characteristic Kα fluorescent X-rays (K-L2,3 lines) are emitted by the 2p→1s electric dipole transition after one of the 1s electron photoionization, Though the probability is less than 0.01, one of the 2p electrons is excited into an unoccupied discrete or continuum level simu...

a simple and green synthetic strategy to prepare bao/tio2-zro2 as a solid base catalyst was reported. these materials with various amounts of bao were prepared by the adsorption method. the physical and chemical properties of bao/tio2-zro2 were investigated by x-ray diffraction, x-ray fluorescence, specific surface area and bjh pore size distribution, ft-ir spectroscopy, scanning electron micro...
