Measurement of K X-ray fluorescence cross-sections, fluorescence yields and intensity ratios for some elements in the atomic range 22less-than-or-equals, slantZless-than-or-equals, slant68

The Kα, Kβ, and total K X-rays fluorescence cross-sections, as well as the average fluorescence yields for 24 elements with 22less-than-or-equals, slantZless-than-or-equals, slant68 have been measured at an excitation energy 59.54 keV γ-rays from an Am-241 filtered point source. Furthermore, the IKα/IKβ 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 IKα/IKβ 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
