Measurement of K X-ray fluorescence cross-sections, fluorescence yields and intensity ratios for some elements in the atomic range 22 <or= Z <or= 68.
The Kalpha, Kbeta, and total K X-rays fluorescence cross-sections, as well as the average fluorescence yields for 24 elements with 22 <or= Z <or= 68 have been measured at an excitation energy 59.54 keV gamma-rays from an Am-241 filtered point source. Furthermore, the I(Kalpha)/I(Kbeta) intensity ratios for these elements have been investigated. The K X-rays emitted by samples have been counted by a Si(Li) detector. Experimental values of the K X-ray fluorescence cross-sections, fluorescence yields, and the I(Kalpha)/I(Kbeta) intensity ratios have been compared with theoretical values. In most cases, there is an agreement between the experimental and theoretical values within the standard uncertainties.
