The K alpha, K ss, and total K X-rays fluorescence cross-sections, as well as the average fluorescence yields for 24 elements with 22 <= Z <= 68 have been measured at an excitation energy 59.54 keV gamma-rays from an Am-241 filtered point source. Furthermore, the I-Ka/I-K ss 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-Ka/I-K ss 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 (C) 2007 Elsevier Ltd. All rights reserved.
